Repairing Boot Camp after creating new partition

Hello! I was wondering if you guys could please take a look at my thread. I ran "sudo gpt -r -v show /dev/disk0" as well as "sudo fdisk /dev/disk0" already and posted the results. Any help would be greatly appreciated

Bootcamp partition Black Screen of Death after restore from DMG file + mbr rebuild

Guys none of the solutions suggested by the bootrec.exe tool worked for me.

So i'm just thinking maybe i need to reinstall bootcamp? or erase my bootcamp partition and restart it from scratch?

thank you for your help though

"none worked" I don't know what that means other than presumably it doesn't boot Windows. But tell us what did happen for each step, because that'll give a clue where the problem is.

Does the Windows "BOOTCAMP" volume mount (read-only) in OS X? That is, do you see the Windows drive in the Finder and can you see your Windows files in it?

Before the installation gets thrown away, please look at http://windows.microsoft.com/en-us/windows/what-are-system-recovery-options#what -are-system-recovery-options=windows-7

ok so this is what i did :

I put the windows 7 cd in the dvd drive

Selected a language, time, currency, keyboard, clicked NEXT
Then clicked 'Repair your computer"

then there was a box that said "use recovery tools that can help fix problems starting windows"

*"select the operating system that you wanted to repair,but there were none so clicked NEXT

Clicked Startup Repair

new windows said : Operating System: Unknown or (Unknown) local disk

Startup repair cannot repair this computer automatically , i then clicked "send information about this problem (recommended)"

In the diagnosis and repair details this is what i got:

Startup repair Diagnosis and repair log

Number of Repair Attempts: 1

Session details: System Disk = (device) Harddisk0

Windows directory=

AutoChk Run= 0

Number of root causes= 1

under " Test performed" i had

Name: Check for updates

Result Completed successfully. Error Code= 0x0

Time taken= 31ms

Test name: System Disk text

result completed successfully> Error code= 0x0

Time taken=15ms

Boot manager is missing or corrupted

Repair Action: File Repair

Result Completed successfully. Error Code=0x15

Time taken= 0ms

so i went back to the previous page with all the different options: Startup repair, System restore, System image recovery,Windows Memory Diagnosis, command prompt

Couldnt choose "system restore" as i wasn't able to choose any OS.

Clicked Command Prompt

typed Bootrec.exe /fixmbr, pressed enter

"The operation completed successfully" ,so i tried to reboot and press ALT/option , clicked on the Windows Icon but got the error

'A disk read error occured'

Boot Windows CD again, command prompt

typed Bootrec.exe /ScanOS ,pressed enter

"Successfully scanned Windows installations"

"Total identified installations : 0 "

"The operation completed successfully" , then reboot

so i tried to reboot and press ALT/option , clicked on the Windows Icon but got the same error

'A disk read error occured'

same for Bootrec.exe /RebuildBcd in the command prompt>

i then tried

bcdedit /export C:\BCD_Backup

but it said "the store export operation has failed.

the system cannot find the file specified''

That's pretty much all i got the same error from trying to boot windows at the startup..

The windows drive "BOOTCAMP" does not show up in the finder when i type it as "BOOTCAMP"

however i can still see it as a second drive in the left hand side under "device"

- shows a folder in startup disk "windows bootcamp" instead of showing a drive

- third partition in Disk utility ( 3partitions in total Max osx, Linux, Windows) as i deleted the Linux Swap partition that i had created.

Do you want to start a separate thread for this? Also can you post the output of

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

Do you have a good Windows backup (not a Mac OS X disk utility image or a time machine)?

How much effort do you want to spend in fixing this? Do you have an option to re-install and get all your data and applications?

If ALT/Option key is pressed during power-up and Windows is selected from the icons AND the Windows CD/DVD is in the Optical drive, does it boot windows and allow you to repair the installation or re-install Windows (Windows OS Only)?

Loner T, I do not mind spending time on trying to fix this at all, i've already spent quite some time

I have got now my bootcamp data on a usb drive.

Now: - If ALT/Option key is pressed during power-up and Windows is selected from the icons without the Windows CD/DVD in the Optical drive

i get the error: A disk read error occurred.

-If ALT/Option key is pressed during power-up AND the Windows CD/DVD is in the Optical drive,

i can see choose between three Hard drives: Mac os, Recovery HD, Windows, and two CD icons: Windows CD, EFI BOOT

if i select Windows hard drive or Windows CD i get the same message error "A disk error occurred".

I can only start windows CD by rebooting and holding "C" for some reason.

output of sudo gpt -vv -r show /dev/disk0 gives :

gpt show: /dev/disk0: mediasize=320072933376; sectorsize=512; blocks=625142448

Finally solved the problem,

i deleted one of the partition that i had created (linux) so as to resize the mac os x partition to what it was like before.

Hence there are only two visible partitions in disk Utility now Mac OS x and Bootcamp.

Then typed in command:

sudo fdisk -e /dev/disk0

setpid 4

07

flag 4

write

then tried to reboot (without windows CD) , held ALT/Option button , selected Windows and running windows 7 seems to be working fine now.

Thank to both of you Christopher Murphy and Loner T.

But does it mean that i will have issues creating multiple partitions? because i still want to fully install Linux and not run it on VM..

Glad to see it work.

The limitation is due to the Bootcamp implementation using an MBR on a single disk.There is a little bit more freedom when using multiple disks.

If you need to run Linux, one option to consider is an external storage device so the partitions which use Bootcamp on the main disk can hold OSX and Bootcamp. Another option is to add an additional disk into your machine, and install Linux on the second disk, or move Bootcamp to the second disk and use the first disk as OSX/Linux.

So at the moment if i either try to add an additional partition by shrinking Mac os partition or Bootcamp i will end up with the same issues?

Yes. A single disk and the MBR implementation requires 4 partitions as maximum (as you can see in fdisk output). You can create your own Hybrid MBRs, but they are fragile and some Disk Utility operations can cause problems, including data loss.

Using a second storage device, is probably the best solution (with least amount of issues), if you do want to use VMs.

This should have said "if you do NOT want to use VMs".

Do you know if i still need to create partitions using rEFInd?

i quote from Christopher Murphy "

"rEFIt is no longer maintained you shouldn't use it. Use rEFInd instead, which is a fork of rEFIt and is actively maintained by Rod Smith who is also the author of GPT fdisk (a.k.a. gdisk). You'll want to read the instructions on how to configure it to use the linux EFI STUB bootloader, that way you don't have to deal with GRUB. rEFInd is a boot manager, strictly speaking it's not a bootloader. It dynamically finds the Windows and OS X bootloaders, and with minimal one time configuration it can locate linux kernels (including new ones when you do software updates) and use the built-in EFI STUB bootloader that's in the kernel itself."
