Re-sizing start-up partition

I have just removed an unwanted partition on my 1gb hard drive but the extra space has not shown up on my main OS partition. I have tried to increase the size in Disc utilty but nothing happening. Someone suggested using the imac start up DVD and go to disc utilities to solve the problem. However since upgrading to mountain lion the DVD is no longer recognised. If it helps to know I do have time machine back-up for my hardrive. Any thoughts?

You don't need any Add-On program if you are removing a Mac type partition, IE Not a Boot Camp Windows partition.
It is all done in Disk Utility. But it can only work with partitions Below the top OS partition. If you have a partition above the one the OS is installed on then you will need to use some type of external boot soyrce to Re-Partition the drive as One Partition and then restore from TM backup or reinstall the OS.

Windows 7 not starting when partition is finished.

I'm using a Macbook pro 15-inch 2011 using OSX yosemite trying to partition windows 7 ( 64-bit ). Whenever I try to partition my hardrive via book camp assistant and the partition part is successful but windows will not start when my mac restarts. I'm using an external cd drive which works. Its reading the disk but it windows simply won't start and I'll be stuck looking at a blank screen with a type symbol on a black screen similar to what you will find in any windows os. Please help.

Is this what you have - MacBook Pro (15-inch, Early 2011) - Technical Specifications?

You cannot use an external Optical drive. If it is non-functional, you will have to fix it or replace it. This is because BCA sets the boot to be from the internal Optical drive physical address based on your Mac's Model Identifier. This is true for all Macs which have a built-in Optical drive.

Re-sizing your Bootcamp partition

Is there a way to re-size my bootcamp parition? I partitioned out 25gb & am thinking that was a bit much for just occ. gaming. I'd like to maybe cut that down to ~ 18gb & recover some of my HDD space.

You could try the command line diskutil:
F.ex
$ diskutil resizeVolume disk1s2 limits
then
$ diskutil resizeVolume disk1s2 20G
Or something like that, not sure if it really works though. I'd be sure to backup any partitions before attempting it. Failing that you can just use diskutil to image your windows partition, then use the bootcamp assistant to restore the osX drive to how it was pre-bootcamp partition and start again.

Rapid Start: Hibernation Partition Size with 24 GB RAM

I ordered my W520 with 24 GB RAM and need some advice how to size the hibernation partition to use Intel Rapid Start Technology. By default the hibernation partition was 8 GB which is the standard RAM.
What size should I use 24000, 24576 or just the size of my hiberfil.sys (only 18.541 MB)?
I'm afraid to waste SSD space.

You can't create a partition for the hiberfile. As far as I know it HAS to reside on C: :-(
Personally I disable hibernation all together and use sleep-mode instead.
Sleep-mode = freeze and poweroff everything except for the RAM, which draw a tiny bit of power to keep its contents. Resume from sleep-mode is instant.
When I don't swiftly turn off the computer to sleep-mode, I turn it off for real. I think this is a good idea, to restart the Operating System and all running apps every now and then.
I think the shutdown time and startup time with compressed hibernation enabled is not that much faster than an orderly shutdown or boot.
By disabling hibernation, you free up many GB on your SSD.
To disable Hibernation and free many GB from C:
Start CMD.EXE with elevated privileges and type:
POWERCFG -H off
As kayphoonstar writes, you can reduce the size of hiberfil.sys by 50% by enabling compression
Start CMD.EXE with elevated privileges and type:
POWERCFG -H -Size 50

NB305 - how large does a win 7 starter OS partition need to be?

Hi,
I tend to re-image the OS of my computers fairly regularly, and plan to do a clean install on a NB305. Given that it had a win 7 starter OS on it (32-bit), I'll be putting the same back on, but on a separate partition reserved only for the OS and program files. I'm not planning on putting any huge programs on it, just word 2000, thunderbird, itunes & firefox, and maybe a few others.
How large should I make the OS partition (I'll probably just keep the pagefile on that partition too)
Thanks.

I would make at least 50 GB. The OS itself will use about 20. The 64-bit version takes about 4 more.

RE : Start Partition

Hi Luis,
The easiest way would be to create a TOOL-based SO,
with the task-initiation
code in the Init() method of the TOOL-class. Put this
SO in the partition
you are interested in. When the partition comes up, the
SO is created, the Init()
method is executed and your task is started. Bingo!
Of course, if there are already other SO's in the same
partition, you will have
to consider order of creation etc.....
Hope this helps!

It is running now using the safe boot BDAqua suggested.
Not sure what all else I need to do so I won't have to safe boot again when I need to see my old iMac desktop again and retrieve files, some of them Quark 4 files that the iMac booted OS 9.2.2 to run.
I've run Apple's Disk Utilities on it via Firewire for repairing disk permissions and to verify the disk.
As for the Tiger disk, I borrowed the OSv10.4.11 DVD (Black) to install it, and called Apple to get my own disks. Since it is a single disk for the DV version, they told me there is no charge for it and are it sending to me.
Thanks for responding, Dale.

Bootcamp partition exists, but won't start

I needed a Win exclusive program, and when I went to fire Win7 up by pressing "alt/option" during startup, Bootcamp was missing. When OS X starts, the Partition is on my desktop. I also tried using BootChamp to force into Win7, but when the computer tries to start it, I get a black screen with "No bootable device -- insert boot disk and press any key"
Bootcamp appears in Disk Utility, and the Startup Disk Pane in System Preferences, but can't get it to load Windows with the same "No bootable device" message.
Any ideas?

Well it seems that is not what is happening now. Somehow your Win7 install got corrupted or damaged or removed.
The only thing you can do is reinstall Win 7.
Or you could try a Repair install by booting to the Win 7 install DVD and Run Startup Repair (I've heard you have to run it 3 times but not sure as I've never had to do it myself).

Ensuring my partitions are the *exact* same size

I want to partition my primary hard disk such that it has numerous partitions that are the *exact* same size. I want to be able to copy them around and onto each other (via dd) so it is imperative that every partition equal the others in size.
I've determined that I want my partition size to be 17211 MB. So I'm using fdisk to create partitions of that exact size. Namely, I wiped the partition table, then started creating partitions using the first available cylinder and using +17211M for the size. Then using the 'p' option I listed the new altered partition table and now under "blocks" the number of blocks for the new partitions is identical (16812022+, to be specific). So far so good.
However, I've run out of primary partitions and would like to jump to using an extended partition. So I created an extended partition using the rest of the disk, then used the first cylinder that the extended partition started on as the first cylinder of my next partition used +17211M for the partition size. However, this time using 'p' showed that my new partition didn't have the same number of blocks as the previous (primary) ones. This problem was solved, though, by deleting the partition and recreating it starting with the first cylinder *after* the first cylinder of the extended partition.
But, I had a problem with the next partion on the extended region. If I start it on the first available unused cylinder and make it +17211M in size, it doesn't show as having the same number of blocks as the other partitions.
I've included a terminal dump of what fdisk is showing me thus far, to help make it clear:
Command (m for help): p
Disk /dev/sda: 81.9 GB, 81964302336 bytes
255 heads, 63 sectors/track, 9964 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 13 104391 83 Linux
/dev/sda2 14 2106 16812022+ 83 Linux
/dev/sda3 2107 4199 16812022+ 7 HPFS/NTFS
/dev/sda4 4200 9671 43953840 5 Extended
/dev/sda5 4201 6293 16812022+ 83 Linux
/dev/sda6 6294 8386 16811991 83 Linux
It's the second partition under "Extended" that I can't get to be the right number of "blocks".
I guess I should ask, to be sure, if "blocks" even has anything to do with size. It seems like partitions with different numbers of blocks should be different in size, but is that really so? Or am I getting worked up over nothing?
Also, on the topic of blocks, what's the + after the block count from some of the partitions imply?

Nothing in specific, just general convenience. My reasons have varied over time. Back in the days of Ubuntu, upgrading from one version to another instead of performing a clean install was a game of roulette, so I'd always dd my Ubuntu partition to another drive right before I went to school for the day (even though the dd would only take about 20 minutes), then come back and upgrade. If the upgrade didn't go as smoothly as I wanted and I didn't deem it worth my time to sit and manually fix everything I'd just restore the old copy via dd (or even just use that one as my primary OS) and wait for a time I wanted to do a clean install.
A while ago I also used to backup Windows to another partition, just in case the current version became infected with something. Never happened (that I knew about, at least) so I stopped bothering.
More recently I've used it for when I'm lazy and don't want to bother undoing my steps. If I install something, configure it, do some stuff and break it, it may be faster to restore with a 20 minute dd than 30 minutes of hacking.
And I can be a bit compulsive in the organization compartment. Ever seen the TV show Monk? I'm nowhere near that bad ( ) but everytime I fdisk -l and I see unevenly-sized partitions all for the same job, I become less than pleased. I've been looking at it for a long time now, and figured I'd take some free time to fix it.
In short, nothing terribly practical, it's just somewhat convenient/organized.

I can't boot to Windows after resizing my Mac partition.

So, I recently decided to resize my bootcamp Win7 partition. This is something I have done successfully before, by:
1) Booting into Macintosh
2) Using Disk Utility to decrease the size of the Mac partition (20GB the first time)
3) Booting into Windows
4) Using Mini-Tool Partition Wizard (third-party) to allocate the free space to the Bootcamp partition.
There were a couple issues caused by this the first time around, mainly the fact that Macintosh didn’t recognize the fact that the free space had been taken, and had trouble reading from the Windows partition. However, I could live with that. I have since rebooted to both Mac and Windows several times without problem.
Recently, I decided I needed a bit more space, and so started to follow the above steps, shrinking the Mac partition an additional 15GB. Only when I went to reboot to reallocate the space, the Windows partition didn’t show up as a bootable option. Confused, I booted back to Mac, and the Bootcamp partition was still there, but renamed “disk0s4”, and unmounted. Reparing the disk failed (“Invalid BS_jmpBoot in boot block: 15921e”). The disk wouldn’t mount (not even sure if it was supposed to be mounted earlier, but that’s what it looks like). It also appears grayed-out in the list of drives to the left. It looks like I can create a dmg from the windows drive, although I haven’t done that yet (I will soon).
Any solutions for this? Although I will erase the drive if absolutely necessary, it would be preferred if that wasn’t the first option to try. I had no problems like this the first time I resized the disk.
(My mac partition is running Mavericks, if that is of any relevance)

How to format and make partitions on my G20?

hello
how are you there...I am try to format C: and I want to partitions it to make it smill it is now 80GB I want to make it 20GB, really I hope to answer my Q as followe:
1- format C: with use windows Pro XP.
2- how I change my operator system from XP Home to pro XP
3- how can I partitions my C: from 80GB to 20GB
thanks
Please ASAP

Hi
If you install the OS using Microsoft WXP full version at the beginning of the installations procedure there is an option who allows you to create the partition C. before the installation starts the partition will be formatted and prepared for the new installation.
You can install what you want. Buy the WXP Professional and install it on your Qosmio. All drivers, tools and utilities for WXP Home and Prof. version are the same.
Make attention about HDD free space for Qosmioplayer. The best tool for HDD prearrangement is a Partition magic. This tool is very powerful.

Can I move my operating system to a different partition on the same drive?

I thought I knew what I was doing when I partitioned my hard drive and installed the operating system and everything else. The other partitions are for documents, photos, etc. It worked well for quite a while but now I find there is not enough free space on my start-up partition (24GB) to be able to do new installations. I have cleared a 50 GB partition on the same drive to be the new home of my operating system. I tried copying all the files in the System partition to the new drive but "Startup Disk" doesn't recognize the copied version. How can I make this work without having to install everything all over again?

Too true. I have been partitioning my drives since the 80's when it was "illegal" and voided warranties as was opening the case on a Mac. Now the cases open right up and you drop and slide in new drives and memory. And it has saved my butt many many many times. You put your operating system on one partition, from what I have read it is best on the first partition of the first hard drive in the chain, Master, if you have more than one drive. I have four drives with now down to 8 partitions with the last two 10.4.x OS's that worked well and my last 10.5 for emergency use, all on one drive in separate partitions and boot to them all the time with no problems. I always keep my last install just in case intact and bootable. It's no different than what is done with BootCamp and running Windows. Then put all your data, files, non-Apple applications on another partition(s). That way when the OS hammers, and it will, all you have to recover is the OS and your data is safe. Thenall you really have to worry about is certain preferences and databases that have to be on the start up partition that won't work when aliased. I have found them, and they are few, and use Backup from the iDisk software library to back these files up to my iDisk nightly. And having the OS all by itself makes back ups so much easier and smaller. But you have to leave Apple applications on the OS partition in the Applications or Utilities folder or the Apple Updater will not see them.
Before iTunes and iPhoto would allow you to link to databases that are not on the start up partition, I was aliasing those files from other partitions. Then early 10.5 it didn't work as well, now when you hold the option key prior to starting up in iTunes and iPhoto you'll get a window to go find or create any of many databases to run off of. I have done this for years with Apple, Microsoft, Macromedia, Adobe and many other applications.
So far my largest OS has been 14.6GB after I installed GarageBand and it loaded a ton of instruments on to the OS partition. I have been through this before and found them and moved them off to another partition and aliased them back and GB works great. Otherwise, even in 10.5.x you can have relatively smaller partitions. And yes you want room to grow, if even just scratch disc space that some applications will not let you choose or go off the OS partition. So I hover around 25-30GB partitions and have never gotten close to getting more that 60% full, fulfilling the 10-15% free space axiom that seems to get larger with every update. I have read here that several people that had taken their machines to an Apple where they replaced drives saying that the techs partitioned the drives and said that the minimum for 10.5.x was 12GB. As the updates flow, that will vary probably up. Plus Apple has some bloated applications and a ton of things that you'll never need or use that take up room that are a pain to find, like unnecessary fonts. A little extra space is always good.
I use CarbonCopyCloner to make compressed back ups and bootable clones. The older versions would not copy files that would be easily rebuilt when you booted that OS, thus cleaning up the clone/back up by cleaning/omitting files that normally get damaged. Not sure if that is part of the latest versions. I think they copy everything. Another great thing is that Apple installers and Disk Utility and can use them to restore or migrate from. Because of CCC, I now have it down to 10-15 to restore a crashed or failing OS from parts. I have yet to loose anything, except time in having to deal with an OS that sometimes has a mind of its own.
As you play around as I did when I was waiting for an Apple Tech Rep, and reran the Combo Updater back over a wonky install, to find out if you could do that, it was done and worked great just as he returned and said no one there knew. I told him that I did and it worked great. We kept in touch for a couple of months to see if anything weird happened, which it didn't, and now it is suggested and common practice. Just as the Tech's and I whispered under our breath in the 90's about partitioning. Now they suggest it and Apple will talk to those that have partitioned. As you see needs and experiment you'll learn (trial by fire) and all this will become second nature. So don't think this is too much and go for it. Just make sure before you are completely comfortable, have another drive, I use 25GB Rewritable Blu-ray Discs, to do regular normal, CCC, back ups until you get the hang of it. This method yields 6-8GB compressed archives. Then you'll have a place for your stored back ups and whatnot. I was keeping up to 5 iterations, i.e.: 10.5.1a, b, c, d and e. Once my paranoia subsided I pared it down to two since I could easily recover the small amount that I have to now from small back ups that are mostly aliases relinking files that are safe on other partitions.
So yes you can put/clone the OS to another partition. Just make sure you cover your bases, use an application made for cloning/backing up (CCC) and label your installs as not to have the same name on two OS's or you'll have a bit of a problem off the top remembering which is which. I'm on 10.5.5C2.
Good Luck and Happy Partitioning.

How do i resize windows partition?

I am sorry if this sounds like a question that has been answered numerous times, but the answers I have read thus far have not helped me at all. I am more confused than ever and would appreciate anyone who can dumb this down so that I can spend the next few hours methodically: 1. resize the boot camp partition from 40GB to 80GB. 2. Install Windows 7 3. Get on with my life.
Now, the Windows side (NTFS) of my MAC Book Pro doesn't have much on it and I have backed up the documents to an external hard drive. The apps on it can be reinstalled if I have to. Since my Windows 7 is an upgrade to awful Vista, I guess I have to reinstall Vista before I can install 7. I have read about WinClone and quite frankly don't understand at all what to do. I want to know if it would not be simpler to remove all apps and docs from the windows side, then remove the partition completely and start anew? If so, does that mean that I would use disk utility in OS to partition the drive? OR do I start BootCamp, partition, then install Vista?
Thank you.

don't use disk utility to do anything with the windows partition. it should only be modified using bootcamp assistant.
if you don't care about keeping your current windows install you can do the following.
1. run bootcamp assistant and remove the bootcamp partition.
2. then run bootcamp assistant again to create a new bootcamp partition of the size you want.
3. from here you need to install windows 7 on the newly created empty bootcamp partition. if your windows 7 can only be installed over an existing vista install you'll have to install vista first.
I'm really not familiar with windows upgrade processes and I'm not sure if this is necessary. also, keep in mind that even though many people have installed windows 7 in bootcamp, it is not yet officially supported by apple. apple will release windows 7 drivers for bootcamp later this year

What do I do if I have lost my MAC-installation CD and I want to do the partition of my MacBook Pro 15" i7 quadra-core?

Hey guys and girls.
I have bought the Windows 7 Home Premium, because I use some programs for my study that can only run on Windows.
I have started the partition and finished installing, but the Windows system doesn't communicate with the drivers.
So I went through the internet to find some info about this, and I found out that I need the Install-CD for my MacBook Pro to install the drivers on the Windows system.
My problem is that I don't have the CD.
Is there a way to finish the partition without the Cd or a way to get another CD?
Thanks, Joakim Østergaard from Denmark.

I think you need to re-read this document, paying close attention to how to make the DVD to install the Windows drivers:
http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.7.pdf
Your computer did not ship with any DVD's, thus there is nothing for you to get, nor is such needed.

RE: NT Server Reboot and Forte Partitions[Ref:C943460]

Hi Bradley.
At our customers, we need one of our Forte applications to be running for data
communications to take place. After a reboot, we need this application's
partitions to come online. The way we did this (as you suggested) was to use a
BAT file, and then install this as an NT service (we used a utility that comes
with the NT resource kit - srvany).
This works fine for us. One of the issues we had was that the partitions tried
to come online before Oracle was running - this resulted in the dbsessions
failing and the partitions not coming online. We got round this by preceding
starting the partitions with a loop that polled Oracle until it was up. Needless
to say, piping all output to log files was essential for us to figure out what
was going on.
Hope this helps,

I have a system administration question for users with NT servers in

server which I would like to startup when the server is rebooted, then
what are my options for scripting this to happen automatically?
Currently the only Forte process on the server which starts up
automatically is the Forte node manager, through the installed NT
service. I have been contemplating setting up a BAT file process as an
NT service which would wait for the Forte node manager service to start,
and then execute an fscript file to start the required forte partitions.
How is this situation being handled in other environments? Thanks.

Hi Brad,
I am not sure if this is the right solution in the long run, but if you
login into NT after reebot you can create a simple client that "pings" your
service objects and put the shortcut into the Startup Group. I think such a
client may also be useful to monitor your Forte server for application
specific parameters, instead of relying only on logs/econsole.
