Windows boot option icon disappear!

Hi, I successfully installed Windows XP SP2 with bootcamp.
I started successfully Leopard and Windows many times, then I installed VMWARE Fusion and I choose to use the fisical Windows partition as a virtual machine.
Now I can choose to start windows or leopard only from bootcamp options in the preference of leopard or systemtray in windows: pressing "alt" button at startup shows me only MacOSX System and disappear windows disk Icons....
How can i reconfigure boot option to show the windows icon too ? I don't want to reinstall beacuse it runs correctly ! it seems only a boot configuration...
The console of leopard report something as com.appl.system service xml boot options do not match...
Sorry for my bad english and thanks in advance for your help!

I guess, I have to explain more...
I know the way of selecting the boot drive( the way you mentioned)... My problem is after creating new partition with disk utility... I cann't any more boot to Win at startup. It seems that the Win startup partition is removed, but when I check it from OS in my FINDER, I can see the bootcamp partition and all my date inside..
So, I need to know how can I again activate booting option to Win at startup(or something like this)

Updated software on Macbook Air and bootcamp partition disappeared. Windows boot option no longer appears. Can I get it back and the data?

Amy, is there a chance they could both be Syncing to another device that has the data erased?
What are the sizes & modification dates on the files you found?
Could be many things, we should start with this to be safe, though 2 different ones would seem unlikely to be this problem...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

Partition is there, but Windows boot option is gone?

Hey folks, I'm having a small issue with bootcamp.
Not too long ago did I have Windows running just fine on my Mac; everything was up to date, I managed to install 7 and upgrade to 8.1 just fine. Everything was good until one evening I open my Mac up, there is a command line that states "no bootable device." I don't believe I had installed Yosemite because last time I shut the Mac it was in Windows. I found a thread from another user here, and followed LonerT's suggestions and managed to get Windows back as a boot option, but the command line still pops up with "non-system disk."
The bootcamp partition is still on my HD with everything installed, so if there's some way I could get this back to how it was without having to go through the hassle of erasing the partition and starting anew I would be greatly appreciative.
Thanks!

Whoa, LonerT!?

I thought the corestorage command was a bit odd so I looked around the web to find out what it means. It doesn't sound promising.

Lost Windows 7 boot option after creating new partition

First of all im new to Mac os.
i have installed windows 7 using boot camp and after it i tried to create a new partition from the main mac partition and it was created successfullly however now the windows 7 boot option is not available for some reason.
how can i have this option back?

You broke it by adding the extra partition, remove Boot Camp (read the directions as to how) and start again. Do not add partitions next time.
Do not use Disk Utility to remove the Boot Camp Partition, use it to remove any extra partitions.
Backup your machine now.

Bootcamp - Create new partition and format in Windows 7

Hello All
I have Windows 7 installed on my sons MacBook Pro.
The Drive is partitioned at 500GB for Windows and 300GB for Mac.
In windows, I need to shrink the Windows drive, and then create 2 extra drives from it.
However, I can shrink the drive, but when I try to Format, it tells me that it cannot find the drive, and then it changes the drive types to all "Dynamic" including the Mac Drive.
And once this happens, I can no longer access the Mac drive during Boot, and windows will not load, as it cannot find the drive during windows boot up. And which point, I have to restore the system and it takes up to 6 hours to installed Lion, as my Internet is slowing that a cold winters day.
So, my question is the following.
How can I successfully shrink the drive.
Then Partition the FREE space
Then Format to NTFS without loosing drive type and integrity?
Thanks All

I ask because what you want to do can be done right from within Windows if you're creating two more NTFS partitions out of the original.
In a single disk system, the MBR looks like this. Even Windows cannot add an entry, unless this Hybrid MBR is manipulated by hand prior to the partition creation. For example, one can create the '0xEE' entry as start=1, size=1454211071, which then allows Windows to create two more entries. If that is done by hand, the GPT and MBR are now out-of-sync. which means OS upgrades or anything done in Disk Utility will cause a data loss or create Windows boot issues.

If the OP really wants a clean installation, pure EFI of both OSX and Windows is the best solution.

Repairing Boot Camp after creating new partition

I'm running OS X 10.8 and Windows 7 x64 Pro.
After properly setting up Boot Camp to dual-boot Windows on my Mac mini, I decided to test whether or not it was true that creating another partition (a data partition for OS X) would interfere with Boot Camp. Wikipedia claims it does interfere but without citing a source, whilst the Boot Camp documentation itself only specifies that the disk must be a single partition _prior_ to setup - there's no mention of whether the disk must be _kept_ that way afterwards.
I opened Disk Utility, reduced the size of my OS X parition from 420GB to 80GB, and created a new partition in the unallocated space. Here's how it looks now:
When I attempted to proceed with the process, I did receive a warning that doing this (and I quote), "may" cause problems with Boot Camp. Seeing as it was inconclusive, I thought I'd give it a shot - nothing ventured…
Of course, it borked Boot Camp, otherwise I wouldn't be posting here. Whilst OS X boots just fine, the Boot Camp partition now no longer shows up in the Startup Manager, though it does in the Startup Disk prefPane. If I do attempt to boot into Boot Camp, I receive the following message on a black screen:
No bootable device --- insert boot disk and press any key
The advice given to someone who had this same problem was, "fix your damaged Boot Camp volume." But I'm at a loss as to how to do that.
So, anyone know how to proceed now so that I can keep my partitions as is, whilst fully restoring normal Boot Camp functionality?

You can not create another partition on a drive containing a Boot Camp partition. You now need to erase then format your drive. Reinstall OSX then reuse Boot Camp Assistant to create a new Boot Camp partition. Reinstall Windows. Ensure you copy off all your data before erasing and formatting the drive.

One Key Recovery 8.0 - windows 8.1 - create new partitions

Dear Members,
Looks like I am again back to the start of the loop regarding the one key recovery after checking with Lenovo customer support. Can you help me on the below. However, I still feel that the well documented procedures for One Key Recovery 8.0 is missing rather than just explaining the navigation. I have z50-70 59436412 laptop with prebuilt windows 8.1
Apart from other (recovery,OEM, others) partitions I have 2 partitions which are C (windows 8.1) 890 GB and D (drivers) 25 GB However I want to create additional partitions (4) to organize my files. Can I directly go to diskmanagement and shrink the C volume to around 300GB and then create more number of partitions from the available space?
Is it mandatory to create a recovery media pendrive with bootable OS? As per Customer support "YOU NEED TO MAKE A RECOVERY MEDIA PENDRIVE WITH BOOTABLE OPERATING SYSTEM AS CHANGING THE NUMBER OF PARTITIONS WILL BREAK THE OKR METHOD AND OKR WILL NOT WORK!!! i.e., I will not be able to reset my laptop to factory settings when I create more partitions. Can some one confirm this? Also, if I make a bootable OS, and during restore doesn't it prompt for a key to make the windows OS as genuine?? Can I make a bootable OS on multiple DVDs (as one DVD isn't enough)? Is the approach same as in the case of making on one DVD?
I haven't took the system backup. I want to make more partitions (shrink C volume and create 5 more partitions for easy maintenance). Will I be able to restore my system back to factory settings (using NOVA key) eventhough there is number of partitions mis-match (initially 2, now around 6 paritions)? I am not worried about my data, as I will have backup of important files into external hard disk which I will restore later using other software
Can I have partition based backup and restore using OKR 8.0?
If I have a system image after creating all the partitions then will I be able to restore using this image without issues?
Say if the harddisk is crashed and I have the backup image on external OS. Can I restore the image back on the new harddisk? Should the number of partitions be same? Also, should the size of each partition also be same?
Suppose I have a partition on harddisk itself to store backup images (img1,2,3,4,5) and when I need to restore to image 3, and after successful restore, I am sure that will loose the image 4 and image 5 on this partition. Can I be able to restore my system to say image 2 if needed in future when I am running on image 3. Also, is there any limit on the number of system restore for a specific image?
Awaiting your suggestions. Sorry, if this is been asked repeatedly by any others.
Thanks,
Cheeli.
Solved!
Go to Solution.

Disclaimer: I dont use OKR .
Based on the documentation and posts I have read about OKR, it requires your HDD partitions to remain the same size as factory shipped. What the Lenovo customer support center stated to you is correct! ANY change to the C or D partitions sizes will cause OKR to FAIL. (there are posts stating such failure after changing the partition sizes).
The OKR create recovery media is designed to work with a Pendrive. It will not work with a DVD.
You could try running Windows backup with the backup being stored on the C drive or on a second HDD/usb,etc.
FYI. A HDD can only hold 4 regular partitions. Above 4, you would have to allocate EXTENDED partitions.

Adding beneficiary to Optional Life insurance in ESS creating new record

Hi,
We have a insurance plan called Optional Life Insurance. IN the portal (ESS) when a employee adds a new beneficiary to this plan, system is creating a new pending record by delimiting the old record to end of that month. The problem is the newly created pending record is asking for EOI (evidence of Insurability).
Adding or deleting of beneficiaries in portal is resulting in EOI being asked. When the same process is done through GUI, there is no problem.
The EOI setting for action in IMG for this plan is "Create Pending record for desired option".
(But this setting is only for enrollment, this should not be reflected when beneficiary is added or deleted, right?)
Regards
Kiran.

Anyone faced such problem before? Any clues?
Thanks.

After installing lion, windows 7 boot option disappeared.

I had a macbook with snow leopard and windows 7 together. Yesterday I installed macosx lion. After installing it, windows 7 selection disappeared in boot menu. I tried to select boot options by pressing "alt key". I saw a new partition which is Recovery HD. There was no bac up files. So what happened to my windows 7 part? How can I restore system?
I tried to use disk utility in lion. I realized that the name of the windows 7 part was changed, now it is disk1s4 but before it was disk0s3 etc..
I removed my macbook HDD and attach with as external HDD to a desktop computer. But I could not find any solution.
In a forum, Someone suggest to create RAW diskimage by using a program named "active and undelete"
Firstly delete windows 7 partition on HDD and create new partition. And then set up it with windows 7 DVD and use RAW diskimage and restore your old settings.
is this logical?
Or is there any simple way to rescue my system? For example If I reinstall Snow Leopard, come my windows 7 partition back?

I could not remember this selection but if I choose one, I choose complete install..

Create another partition in Windows

Hi,
I'm using Mac OS X Snow Leopard, and I installed Windows 7 using Boot Camp.
I want to create another partition for Windows for personal files.
How can I do that?
I used some Windows applications such as Acronis but it was unable to identify partitions.

NOT on the same drive!
Buy a PC. People tend to do what you want (I don't but I only use 35GB for system under Windows and about same for a Mac OS X volume).
Boot Camp and Windows on Mac is a one size fits all and only supports
GPT 200MB
EFI 128MB
Mac OS HFS+
NTFS
4 total - MBR is a subset of GPT (all drives with GPT/GUID have at least a zero size MBR protective entry).

No Windows Option on Startup

Does anyone have this issue? When I press the option key on startup, I only have the Mac OS option to startup. If I want to start up in Windows, I have to change the option in the preferences, then restart. AND THEN, change the preferences back in Windows (to Mac). I want my main startup to be Mac with having the Windows just "an option" during startup. Looking at all these other issues, I guess I can call myself lucky because it's not a terrible problem. Just wondering what the deal is.
Also, anyone know more info on the time/clock setup in Windows?

Had the same problem and I found the fix on another Apple board. I first formatted the Windows drive in Fat 32. That some times can make the Windows disk not appear on startup. So I removed Windows with boot camp,then reinstalled Windows in NTFS disk format, as the post said and now it works perfectly! Have zero problems.

Windows 8 does not have a USB boot option

QuestionHow can I boot my Windows 8 laptop from a USB device? I created a recovery disk on a USB thumb drive.
So far I have:
Entered into the UEFI (BIOS) and set USB to boot first.
Disabled secure boot.
I tried to reboot using the general setup options for startup in the windows settings page. I choose boot from USB through the UEFI, but got an error message that system does not have a USB boot option.
To confirm I also created a bootable DVD with an ISO burner, but my laptop cannot detect a DVD boot option either.
I assumed that the firmware of the UEFI for this computer allowed a bootable USB but in practice I cannot seem to get this work.
AnswerTo assist with not being able to boot from a USB device on a Windows 8 laptop, perform the following:
Plug in USB bootable device.
Hold down F12 when restarting and access UEFI menu (option is below drive list). If system is set to fast boot, CLICK HERE for instructions on entering the UEFI.
Go to UEFI and make USB "1st boot".
Disable secure boot.
Go to the "Advance" Tab, select "System".
Change boot order from UEFI to CSM.
Save changes and exit (F10).
Computer will restart and boot from USB drive.
When finished go back into the UEFI and set defaults then save changes and exit (F10). Windows 8 will reboot normally next reboot.

Done that, only choices are "Set up Firefox to Sync" & "Pair a Device". No ''UNLINK THIS DEVICE". Your turn.
