Partition: Yes or No?
I just got a new 13” MB Pro with Lion installed. The drive has 750 GB.
The drive on my old MB failed, without any warning. ( Grumble, grumble.)
I am wondering whether drive partitioning is a good idea keeping applications on one and data, especially photos and videos on another?
I may have some programs that will not work with Lion.
Since Lion has a partition called “Recovery HD,” If the drive itself fails are all partitions toast as well—just as if there were only one?
Where are partitioning instructions, please?
I am not sure that I like this Brave New World without any media or the push to eliminate optical drives. Someone, please explain to me why these are good things?
Thanks in advance for your help.

Sure, Shootist007 I also have a number of very old computers, as I said. Some are considered actual “door-stops.” Like an old classic car, the issue is one of being able to obtain and repair the failed parts. The fewer moving parts the better. With the new SSD technology things are looking up. That failed drive on the MB I mentioned above will probably be replaced with an SSD. In the meantime, however I have a shiny, new MBP.
As most people have learned, it is not always advantageous to upgrade to the “latest” software since many so-called upgrades are mere window dressing and not really quantifiable steps forward.
I try to get at least 5 years out of a machine and software. That said, there is definitely a lot of built-in obsolescense. Some machines have aged better than others.
Thanks for all the input, guys. I shall probably not partition.

[SOLVED] (U)EFI dualboot Win7 Arch Linux - partitions gone - recovery?
Hi everybody,
I have a slight problem with my (U)EFI dualboot system (Windows 7 and Arch Linux) which used to be configured using rEFInd like it is described in my previous post:
https://bbs.archlinux.org/viewtopic.php … 6#p1300356
<EFI PARTITION> is /dev/sda1 and I used to boot via <EFI PARTITION>\EFI\Boot\Bootx64.efi which then successfully either loaded Windows or Linux kernel.
Thanks to my own stupidity and a recent update of refind I decided to copy the new driver, font and icon folders to the <EFI PARTITION> in order to be up-to-date.
After doing so, the rEFInd boot menu had a third icon which said "Boot via \EFI\Boot\Bootx64.efi" and if I clicked on it a second rEFInd boot menu appeared with only the two icons for Windows 7 and Arch.
So I figured I could delete Bootx64.efi and ultimately did so, unfortunately. Afterwards I couldn't boot neither Windows nor Linux anymore.
Following this I went through my noumerous USB boot sticks in order to be able to recover the Bootx64.efi. Unfortunately the first USB stick was a Windows XP one which has the plop bootloader alongside:
http://www.plop.at/en/bootmanager/thebootmanager.html
Out of couriousity I entered this bootloader and found HDA and HDB (I assume resembling my SSD and my USB stick).
To my knowledge I didn't change anything but after entering the bootloader again I just found HDA left, HDB seemed to be gone. But I didn't think of anything bad happening yet.
Then I found a working Archiso which I booted and using blkid I couldn't find the partitions of my earlier system anymore, only its device and the USB stick:
/dev/sda: PTUUID="..." PTTYPE="gpt"
/dev/sdb1: UUID="..." LABEL="ARCH_201312" TYPE="..." and so on
/dev/sdb2: SEC_TYPE="msdos" and so on
Even within the EFI shell I could not detect any internal drive anymore (only fs0: which is the USB stick)
Using Archiso onboard tool testdisk I could find the old partitions. The correct result of the GPT from testdisk is:

Now the question is: Can I - using testdisk or any other tool - recover those partitions successfully so I will be able to boot again afterwards? I tested and I could mark them as:
P Primary
Any help will be greately appreciated.
Best regards
Last edited by blablubb1234 (2014-07-08 09:20:08)Issue resolved If you care to know how, read on:
Looking at the disk using gdisk was doing no good. Neither of the recovery options in gdisk did the trick.
I then returned to testdisk and restored the partitions (successfully). However, afterwards I was greeted by shell telling me the root device was not found (seems like UUIDs get changed when one restores them using testdisk). Adjusting the PARTUUID for root in <EFI SYSTEM PARTIITION>/boot/refind_linux.conf did the trick and I could boot up Archlinux again.
Windows 7 still didn't boot telling me the required device was inaccessible (probably wrong UUID, too). I could however not restore/edit Windows' BCD using bcdedit, see my post Status: 0xc0000225 boot selection failed; required device inaccessible:
To make a long story short: Removing bcd and running autorecovery from withing Windows RE successfully created a new bcd. Unfortunately, Windows writes its backup bootloader at <EFI SYSTEM PARTITION>/boot/EFI/Boot/bootx64.efi. This file originally was a copy of refind_x64.efi which I need to put at that location to be able to dualboot. After chrooting to my Arch system I could restore bootx64.efi, create a new fstab and everything is running fine now again.
Best regards and thanks for the help. -
NULL partition key in RANGE partition
All,
This is regarding partitioning a table using RANGE partition method. But the partition key contains null. How do I handle this situation? This is because there is no DEFAULT partition in RANGE partition though its present in LIST partition. Will rows with NULL partition key fall in MAXVALUE partition? Seeking your guidence.
Thanks,
...NULLS would fit into the MAXVAL partition yes.

Mac pro boot camp partition cloned to MBP?
i have a 200 GB mac pro boot camp partition with windows 7 on it and between setting it up and getting all my software customized it has been like doing time in a soviet gulag.
if i create a 200 GB partition on my MBP can i clone this from one machine to another?
it would save me a heck of a lot of time and aggravation
TIA
p.s not sure if this makes a difference but my mac pro is a first generation deal that required amy burning a image to disk or something along those lines...Do you know what I do to get 10.5?
Purchase it if the computer doesn't include it.
Also, I don't understand why the drivers are going to be on older software that doesn't have Boot Camp bundled with it.
The drivers are not on a Mac OS X 10.4 CD or DVD. They are on the Mac OS X 10.5 DVD.
Leopard has Boot Camp bundled with it doesn't it? Isn't part of the deal upgrading and improving the drivers?
Yes.
You say in the above "or use up a Windows installation"
This only applies if the Windows disk or license agreement allows you to create a limited number of installations.
Are you saying here that I could also reformat the drive with XP on it?
You could, but there is little reason to do so.
Do I have to reconfigure my workspaces if I do the second option above?
If you erase the Windows partition, yes.

Hi there,
Recently i have been running into a few problems with my Macbook. I have read around and understand sometimes the disk drives can mess up from time to time. I beleive that is whats going on here. I used to be able to burn CDs but now whenever i try and burn a CD it says that there is an error of some sort and the CD will not burn. Also, I used to be able to partition my Macbook all the time and have done so about 3 times and now i cant do that either. I have gone into Disk utility and tryed to repair and verify my drives just for good measure and it still doesnt seem to work
I was wondering if anyone else has these problems or if anyone knows what i can do. I want to try and fix this without having to go into the apple store.

jees pondini... are you on a mission to put down partitioning - this is the second post you've tried to discredit
I see: it's fine for you to post the same thing twice, but nobody else.
... i'll repeat what i said before:
"Only specifically when traveling between the OS partition and the data partition
Yes, of course. But remember that also includes virtual memory, so if the system is busy enough for disk access times to be important, there's likely a fair amount of paging going on, too, so it will be going back and forth frequently.
Still - Large media files will slow down an OS over time as it is updated
Huh? Why? As long as adaptive hot file clustering is working, why would having some large files be a problem
the OS partition can be adequately small and the data partition adequately large, making the physical distance between the end of the OS and the beginning of your data very small... however when considering OS partition size you not only need to consider capacity for future apps but also vm swap files, sleep image and extra space to prevent fragmentation of newly written files. "
Yes, exactly: if you guess wrong, you may make things worse -- either not leave enough free space for OSX, virtual memory, etc., slowing things down; or leave too much for OSX, squeezing the data partition, slowing things down, and making the distance the head must travel greater.
And if your guess is good today, will it still be good in a few months, after you've added more apps and/or changed your habits?
Everything I read says OSX is optimized to work best with OSX, apps and data to be on the same partition. Separate drives of course, is often best.
also adaptive hot file clustering is only for files less than 20 meg in size
That's the limit for automatic defragging.
I don't believe size has anything to do with hot file clustering; OSX will move whatever it needs to. -
iMac with 256ssd and 2t hdd. Should the admin/user folder and all of its sub folders be moved to the hdd or just parts of it? (eg. picture, movies, documents) What is the best way to go about doing this. Also should a 2t hdd be partitioned.
Yes, you can move your user directories to the HD and keep your OSX and Applications on the SSD drive.
Whether you partition your HD or not depends on how much data you have and how you propose to use your HD.
Are you planning to use your iMac as a Time Machine backup volume? If so, partition it off.
Do you have huge data files, eg video, music, photos?
How much of your 2tb drive will be "free" once it is loaded with all your data?
A little more information is required before the optimal configuration can be recommended for your use. -
WinXP partition size on MacBookPro (Parallels)?
I'm planning on doing a partition on my 250 GB MacBookPro which I am going to access using Parallels while in OSX. In the event that the performance on a particular software is not sufficient I plan on booting into the "native" install of XP for better results.
I plan to store (and access) all my files on (and from) the OSX part of the drive.
Does this make sense?
Can anyone give me a good idea of a minimum size for this partition if I am running 3d and 2d CAD? Is there a good way for me to determine this on my own?
Thanks,

Hi Stefan.
Thank you so much for this technical assistance.
Also, thank you for the advice on MacOSX. I can really use this kind of "tangential" advice as I get started again with Mac. I suppose there is a widget somewhere that I can dock to get to the used/unused size of my partition (particularly as I hack my way through "segregating" information between the laptop and desktop, moving image files off my hard drive which I have duplicated by importing into iPhoto etc, etc...?
Not needed that much. The OSX Finder shows you the free diskspace when opening a window or directly on your desktop right underneath the harddisk icons.
Anyway, am I correct in thinking that the 50GB you recommend is exclusive of actual document file storage? I mean, I can plan to store /all/ my important (actual) documents on the OSX side of the partition, yes? The advantage of using Parallels in this case is that OSX partition and XP (or Win7) partition can "talk" to each other fluently in the dual boot configuration is that right?
I am not that familiar with the file sizes of 2D and 3D CAD files, so I assumed that the 50GB would be including those files.
But tis really depends on your personal useage.
Parallels and OSX can share files through 'Shared Folders' which both can access without problems.
And then, I guess I can add up the file sizes of the software I intend to install - and perhaps double or triple this - to get an idea of how much in excess of the 10GB I will be using to install software is that right?
Yes, that's exactly what I meant. Personal 'mileage' can vary hugely.
Lastly, can you say something about the /difference/ in /communication/ between OSX and Win when in "dual boot" using Parallels and when booting directly into the BootCamp partition? I guess that Parallels lets the two OS's talk to each other "fluently" whereas in the "native" boot into Win you can only read or write - er - Win can read and write from OSX but OSX can't read and write from Win (or the other way around?).
Like said, Parallels uses Shared Folders for easy file access between OSX and the Parallels Windows.
With BootCamp Windows you have to use third-party helper. Macdrive in WIndows to have read and write access to OSX partitions/volumes.
NTFS-3G (as an example) in OSX to have read and write access to Windows NTFS partitions. In itself OSX can only read from NTFS WIndows partitions.
Can you install MacDrive so the two can talk to each other when booting directly into Win??
Yes, see above.
Many many thanks,
Jonathan
Hope it helps

Block level backup engine Samsung SSD 840 EVO partition labeled "data"
Replaced the hard drive in my Dell 1545 laptop with a Samsung SSD 840 EVO.
Everything beautiful.
Am running Windows 8.1 - again everything beautiful.
Thought I would run "System Image Backup" (off the File History page).
failed - Microsoft error code 0x80780119
because Samsung Migration tool created a first partition labeled "data"
(don't know whose data this might be suspect it has nothing to do with the OS but is required for the SSD, perhaps for MBR boot purposed.)
This "data" partition is very small and 99% full: no room for the VSS backup requires.
Bypassed that problem with:
PS C:\> wbAdmin start backup -backupTarget:H: -include:C:\
which runs perfectly, except for the warning,
" Note: the list of volumes included for backup does not include all the volumes that contain operating system components. This backup cannot be used to perform a system recovery. However. you can recover other items if the destination media type Supports
it."Hi,
Glad to hear that you've found a workground to backup the data and thanks for sharing the experience here. Regarding to the Samsung "data" partition, yes, as you mentioned, it is related with Samsung Migration software, so I think members working
on Samsung will be familiar with this partition.

Partition disk with fdisk and windows can't be installed.
so I have been running ArchLinux for a few days, have successfully trashed my partition table once and lost everything on my systemdisk sh*t happens thats why I have one drive as system disk
Anyway, since all my partitions died I thought I could repartiotion the disk (I had been thinking of doing it anyway). So I booted the ArchLinux install disc once again and then partition my disk something like this:
/dev/sda1 - ntfs (for my windows xp)
/dev/sda2 - /
/dev/sda3 - /home
/dev/sda4 - swap
All partitions are primary since I only need 4. So off I go install Arch, config everything and so on. Then today I decided to install windows, so I reboot and insert my windows disc and press any key too boot from the CD and then Nothing. My computer just stands there black screen my CD spindowns and stops my HD is chewing away like crazy.
I have no idea what to do, thought my disk has been broken or something so I open my computer case and disconnect all disks attach my secondary disk as my only one just to see if the install starts and so it does (but I don't install because it is wrong disk ). Then I thought it might be the sata-cable who is bad (happend before) so I tried another one and my systemdisk again, but no luck. After that I boot archlinux installdisc and clear my entire partition table, recreate one 20gb ntfs partition make sure it has boot-flag and reboot. Still no luck, so back into linux and remove everything on that disk and reboots. And now the installation finally starts but instead of creating a partition during xp-install I reboot linux once again to create it in fdisk, and once again the installation doesn't start. So now I have cleare the entire disk from partitions again and created my XP partition during the XP install.
WHY can't I create my partitions by using fdisk in linux? and yes I did create ntfs filesystem on my partition (mkntfs or what the name was, exists on archlinux ftp install disc)Yes I do know Windows will overwrite the MBR but that isn't the problem and overwriting the MBR doesn't destroy my partitions just uninstalls lilo (yes I use lilo, to lazy to learn using grub when lilo do the job god enough for me)
My problem is that I can't start the windows install. Here is what I did after ArchLinux was installed
1) Start my computer
2) insert windows install CD when computer is doing the BIOS startup stuff
3) Now I get a message to press any key to boot from the CD, this is from the Windows install CD and I do press the key.
4) Normally I would get into the Windows Install program here But now I Don't, NOTHING happens.
Then I started my search on what was wrong. I have installed Linux many times before windows and I have reinstalled windows lots of times without the need of reinstalling linux or repartition my drive.
In short, after lots of testing my computer does not start the windows install if my first disk has been partitioned with fdisk in linux (havn't tried other partition tools in linux).
EDIT: The windows install starts if I boot into linux and use fdisk to clear the entire drive from all partitions, yes no partitions at all not even one for windows.

Migartion and partitioned disk
Hi all!
I am just about to migrate from my old MacBook to a new one. The old one has its disk partitioned on two parts - one for the operating system and one as a storage.
I am wondering if I just run the migration assistant it will do the same with the new HDD or it will only migrate the OS and later I will have to manually partition the HDD again and move the files?
Please, give any suggestions on how to do it with less troubles.
Thanks!What I will do is that I will get a new MB and after I run it for the first time I will be asked if I want to migrate. I will say yes and will connect my old MB to it using USB (?) or Fifewire (not sure which one of those will be needed) cable.
Then I'd leave the computers to do whatever needed. This is how I already migrated one and all seemed just OK, besides that I had to insert some serial numbers again...
O believe I'll have to do the same this time, no? The only tricky part is what to do with the partition where I store my working files. You said earlier I need not to create any partitions, yes? I am used to those partitions since I was working actively on my PC, but if I somehow get convinced that the OS is secure enough, I may reconsider partitioning the disk.
So, back to the point:
1. How to make the computer ask me if I want to migrate for the second time?
2. After I run the migration assistant on first run of my new MB, I will migrate only the partition with the OS, no? Or I may chose (as I believe I see on the images you so kindly provided) other partitions as well? If yes, my question is if the migration assistant WILL or WILL NOT create the second partition for me?..
Thanks for getting involved with this! Thanks though! -
SSAS 2008R2: Dynamic partitioning via SSIS - is this logic correct?
Hi all,
I'm setting up dynamic partitioning on a large financial cube and implementing a 36month sliding window for the data. Just want to make sure that my logic is correct.
Basically, is doing a process update of all the dims then a process default of my facts (after i've run the xmla to add/remove partitions) enough to have a fully processed (and performant/aggregated) and accurate cube?
Assume I have a fact that has a 'reporting month', 'location key' and then numerous measures and dim keys. It holds the revenue for that location for the reporting month.
The reporting month can never be backdated. subsequent runs can only overwrite the current reporting month or add the next month.
Assume the data warehouse has been loaded successfully. The warehouse holds a 72month rolling history.
Now, to the dynamic partitioning. The fact is partitioned by reporting month and has aggregation designs.
My SSIS package initially does a process update on all the dimensions. My understanding is that this 'flags' which existing measure partitions need to be reindexed.
Then in my data flow:
I run a simple query over my fact (select 'my partition ' + str(billmonth,6) AS PartitionName, count(*) as EstCount from myFact where billmonth > 36months ago group by billmonth order by PartitionName) to get a list of all the partitions that exist
in the data warehouse and that should be in the cube.
I do a full outer merge on the partition name with the equivalent of that but from my cube. I use a script component as a source with the following code:
AMO.Server amoServer;
AMO.MeasureGroup amoMeasureGroup;
public override void PreExecute()
base.PreExecute();
amoServer = new AMO.Server();
amoServer.Connect(Connections.Cube.ConnectionString);
amoMeasureGroup = amoServer.Databases.FindByName(amoServer.ConnectionInfo.Catalog.ToString()).Cubes.FindByName(Variables.CubeName.ToString()).MeasureGroups.FindByName(Variables.MeasureGroupName.ToString());
amoServer.CaptureXml = true;
public override void PostExecute()
base.PostExecute();
amoServer.Dispose();
public override void CreateNewOutputRows()
try
foreach (AMO.Partition OLAPPartition in amoMeasureGroup.Partitions)
Output0Buffer.AddRow();
Output0Buffer.PartitionName = OLAPPartition.Name;
catch(Exception e)
bool Error = true;
this.ComponentMetaData.FireError(-1, this.ComponentMetaData.Name, String.Format("The measure group {0} could not be found. " + e.ToString(),Variables.MeasureGroupName.ToString()), "", 0, out Error);
throw;
(not a c# coder, above stolen + butchered from elsewhere.. but it seems to work)
I use a conditional split to separate the rows where datawarehouse.PartitionName is null (generate XMLA to delete from cube) and cube.PartitionName is null (generate xmla to add to cube). I dont do anything with partitions that exist in both the cube and
data warehouse.
I then perform a process default of the measure group.
I'm assuming this will do a 'process full' of the new unprocessed partitions, and that it'll do a process data + process index of any partitions that were modified by the dimensions' process update. Is this correct? Or do I need to do any other explicit
processing of my measure groups to make sure my facts are 100% accurate?
Thanks.
Jakub @ Adelaide, Australiacheers, i'll switch it to use getbyname instead
The reprocessing of the current month includes steps in the SSIS package flow that explicitly remove the data from the relational data warehouse(delete from) and the cube (XMLA delete statement against partitions)
Yes, I do have other measures groups in the cube.
I have five measure groups in total. Three are dynamically partitioned while the other two have a single partition.
What will happen to new data in the two single partition measure groups? I did some further reading and now my understanding is that a process default might not process the aggregates if there are no dimension changes and new fact data arrives.
I'm now thinking of making my data flow:
1. execute dynamic partitioning XMLA
2. process update dimensions with affected objects included (this'll reprocess existing dynamic partitions that are modified by any dim changes)
3. process default 3 dynamically partitioned measure groups (this'll process any newly added dynamic partitions)
4. process full 2 single partition measure groups - this step might redo some of the work done in step 2., but the measure groups are only a few million rows in one case and a few hundred in the other with minimal growth expected. And what you just said about
changing data made me realise I have the sliding window in these last two implemented via the source script, so I need to do a process full here anyway.
Jakub @ Adelaide, Australia -
i have installed a brad new Xserver Intel Xenon dual core with 10.4.8, and i have manged to get the computer connected to our windows 2000 AD it´s on a windows 2003 server but the ad is in 2000 mode, and kerberized it, and the server is a domain member. I have populated the local group with AD users, and i have no problem to logon from our macs, but when i try the same account from one of the pc´s with XP sp2 they can´t logon, and i get the logfile like this. If i logon with a local server account from the pc there is no problem.

[TUTORIAL] GE70 2OE Installing Windows 7 (OS CHANGE)
Hello Forum,
Here is my very first post on this forum... but I wanted to share my experience with switching OS on the new GE70 2OE-015NL (as the product name says, I'm from The Netherlands )
I bought my GE70 and immidiately wanted to switch my OS to Windows 7... I owned a Dell Vostro 1700 Series and OS switches were never a problem on that notebook... as soon as i started with the OS change I ran into some problems that were difficult for me to fix (I'm not an expert) There were almost no tutorials to find about this, but I managed to fix it!
Before I figured out what to do, I called MSI Support so they could tell me if I could safely remove the BIOS_RVY partition etc. but as soon as I got someone on the phone and I told him that I already deleted the Windows 8 partitions and didn't get Windows 7 to install he began shouting that MSI doesn't support OS changes and that I had to send an email to their tech support so they could decide later on if they would help me or not.... I didn't ask for anything, I only wanted to know if I fkd up my new Notebook or that it would be repairable... a BIG for the MSI Tech Support! After I called I immidiately googled if it was safe to delete the BIOS_RVY partition but there were no such forum posts that I could find.. Therefore I decided to make this post!
REMINDER: this tutorial is for those that find it difficult or are scared to change their OS without knowing what's going to happen.. I had to figure this all out on my own and therefore I want to help other people with similar problems! So maybe it's a bit noob for this forum I don't know.. but please don't hate because of that! ^^
WARNING: THE INSTALLED OS MUST BE A 64-BIT VERSION, ALSO I'M NOT RESPONSIBLE FOR ANY DAMAGE YOU CAUSE TO YOUR NOTEBOOK/NETBOOK!
It is also recommended that you download all the drivers for Windows x64 before you install Windows because the network card won't work because of a lack of drivers so you need a second PC with a USB or you download them before the OS switch and put them on a USB.
Step 1: Make a bootable DVD/USB with Windows 7 x64 ISO on it, this can be done with Rufus for USB Flash Drives or PowerISO for DVD's! (I'm sorry I'm not allowed to post external links so you will have to google it )
Step 2: Restart the PC and when the text MSI pops up you press the DEL (numpad " . " key) and you will get into the BIOS Menu
Step 3: Go to the BOOT tab and select Boot Mode (or something similar) and change the Boot Mode from UEFI to Legacy
Step 4: Now you're Windows USB/DVD should be bootable (Microsoft says that Windows 7 supports UEFI Boot but I tried using multiple ISO's on different USB's and DVD's with different write speeds etc. but I didn't get Windows 7 Setup to boot beyond the 'Starting Windows' screen)
Step 5: When Windows 7 Setup is Booted select your country settings and time format and don't select the Upgrade option but the Custom (advanced) option to install Windows 7.
Now it's getting a bit difficult for most of us... Windows 7 Booted in a Legacy Boot Mode does not support GPT (Guid Partition Table) Disks, those can only be writed upon in UEFI mode. So now we need to change the Disk Partition Table to MBR (Master Boot Record). When you're at the partition menu, format and delete all partitions (yes don't worry you can safely delete all the partitions (when deleting the BIOS_RVY partition the F3 Hotkey function won't work anymore but we don't want that because it will recover Windows 8 but we hate that OS.. that's why we want to change to Windows 7!)
Step 6: Now that all the partitions are deleted on the disk, we can openup CMD this can be done by pressing SHIFT+ F10 in the partition menu of the Windows 7 Setup.
Now type the following commands:
Diskpart
List Disk
Select Disk # (probably 0, because the most notebooks only have 1 HDD)
Convert MBR
Now your HDD is converted to a MBR Partition Table
Step 7: Make a new partition (or more, depends on how much storage you have and want on your C:\ partition, Windows will automatically make some System partition(s))
Step 8: Select the partition on which you want to install Windows 7 and let it install! the MSI GE70 2OE supports Windows 7 x64 so all the drivers for that OS can be downloaded at the MSI website, product info (GE70 2OE) and then downloads -> Drivers.
Step 9: Install all the drivers and you're ready to go!
I hope I helped you with this problem, for me it was kinda hard to figure out that you could safely delete all the partitions on the disk without screwing up your PC.. So I hope I gave you some confidence with doing so after reading this tutorial!Quote from: CanesBridge on 06-August-13, 00:02:42
Hey man
I did this on the new msi ge60 2oc 014ne, which should be pretty much the same. Almost everything seems fine now except for two things.. I still cant det the wireless network adapter working, even though the ethernet works and Ive installed all drivers i could find. Do you have any idea what to do?
Second thing, in the Windows experience index, it gives my graphics card the grade 5.1, but it should be around 7. I installed the nvidia driver and all, so it doesn't really make sense to me... Any suggestions? Thanks!
Oh yeah, and the big foot boot agent message that shows up every time i boot the machine, i cant make it go away... I click shift + f10, clicks disable message and f4 for save and quit.. But it shows up again nemt time i boot... An annoying useless waste of time..
I guess it's pretty much the same indeed, do you have installed the Windows 7 x64 drivers for your wireless adapter or tried to install the Windows 8 ones? That could be the problem? If that's not the case and your ethernet is working, try checking for windows updates and see if it automatically installs the drivers for you? Make sure you installed the AzureWave Wireless LAN-NB114H driver that is available for your PC for Win7 x64, that driver as the name suggests is for wireless connection. Killer Bigfoot LAN is just for boosting your card so it's faster over LAN but the AzureWave makes the wireless connection available.. It worked for me so it should work for you?
If you did this all, try reinstalling it.. If that doesn't work, try formatting al partitions again en reinstall Windows 7 and start with a clean install...
About the videocard rate.. If your having problems with low FPS during gaming (maybe lower than normal) make sure you have installed the MSI driver for your graphic card (don't download it from the NVidia website) If you don't know, you can find all drivers for your device on the MSI website, Products -> Notebooks -> Gaming Series -> GE60 2OC -> Downloads
If the lower rate of the video card didn't cause low FPS I wouldn't worry too much if I were you
Oh, and about the Bigfoot Boot Manager.. I have the exact same thing.. I'm still figuring out how to get rid of it, but for now I went into the configure mode and set the message to disabled and the message time to 1 second (so that 1 second extra boot time isn't that bad..) If I found a solution to get rid of it I will let you know!
Hope I helped you, if not feel free to reply and ask again! We will figure it out together, or with help from someone else on this forum! -
Re-formatting iMac's Corrupted Hard drive..Suggestions please
Because of a failed Optimisation I feel I now have to completely wipe, re-format and re-load OSX onto my iMac's internal HD, but never having done this before I want to make sure I don't end up in more of a mess then I am in right now! So I'd appreciate any advice as to the best way to go about this.
My iMac is a late 2009 27" and at present has OSX 10.8.5 loaded, ( loaded but with many miss-functions ). Prior to the problem the iMac was running OSX Lion, what version though I can't remember.I installed 10.8.5 the other day to see if that would fix things, but it hasn't. It was not a "clean install", just regular one from downloaded OSX 10.8.5.
I have run Disk Utility and TechTool Pro' 7 to try to make repairs to address the problems so far to no avail. Main problems are that my most used applications, FCP-7 Studio, Aperture and Photoshop CS5 amongst others, open but then immediately crash. I've reloaded the troubled applications, de-installed them properly with de-installation app's then clean re-installed them, but that's made no difference. They will not mount.
I reckon there must be a fault or corruption on the HD, probably caused during the Optimisation as everything was functioning well before I did that.
So, the only OSX install disks I have are the original disks that came with the iMac, OSX 10.6.2 and a Snow Leopard Upgrade DVD OSX 10.6. I do have the downloaded copy of OSX Mountain Lion that I pulled from the App Store the other day and that copy is now on an external USB / Firewire 800 HD.
As I said I would like to be able to clean off the iMac's internal 2tb drive completely and install a fresh newer OSX. If I first have to load OSX.6.2 then upgrade via the App Store that's fine, but I'd rather just go straight to Mountain Lion if possible. Whatever works best. Getting rid of any corruption on the iMac's HD is the prime motivation.
All my applications and files are backed up to a 2tb LaCie external drive.The iMac has approximately 900 gb's of content onboard and the rest is free / unused space.
I would very much appreciate all the help and suggestions as to how I can safely go about the wipe and re-installation of a fresh OS. I fear doing this without good advice I could very well "brick" the iMac!
Thanks!
PMI would like to revert to OSX Lion. How can I do this,
Revert to a Previous OS X
would it be possible to install Lion on a separate partition
Yes. Boot into the Recovery Volume again and use Disk Utility to partition the disk.
Is the Installer in your Applications folder? That is where it downloads to. When you start it, you can point it at the new partition and install it there.
