When I select my Windows 7 partition in the Chimera boot screen, it gives me the all-too-common "BOOTMGR is missing: press CTRL + ALT + DELETE to restart"
Before you go on about saying that I have to boot from the system reserved partition or run /FixMbr and et cetera from my Windows 7 install disc, please read everything to understand my situation.
I have two 500GB hard drives. Note that the capacities of partitions are rounded.
sda: GPT
sda1: EFI (200MB)
sda2: Lion (HFS+, 100GB)
sda3: Media (HFS+, 400GB)
The Lion partition has 10.7.3 installed, whereas my user folder is located on Media.
sdb: MBR
sdb1: Ubuntu (ext4, root (/) partition, 256GB)
sdb2: Swap Area (6GB)
sdb3: 7 (NTFS, 210GB)
sdb4: Restore (FAT32, 28GB)
sdb1 has both Ubuntu 12.04 installed and Grub to allow chainloading. Boots perfectly. sdb3 houses Windows 7 Professional 64-bit, installed after Ubuntu. sdb4 has been there before either operating system and houses installers for Windows and post-installation files for my Hackintosh.
I used the partition manager in the Ubuntu 12.04 LiveCD to partition sdb into the 4 partitions mentioned above. I then installed Ubuntu and Grub to sd1, with sdb2 being specified as the Swap Area.
I then proceeded to install Windows 7, disconnecting my OS X drive before doing so. I installed to sdb3 (then formatted to FAT32, which the install disc automatically formatted to NTFS). It told me that Windows might create additional partitions for system files. I clicked on OK.
Windows 7 install went fine and dandy, and thanks to GoingBald's awesome triple-boot tutorial I was able to fix the Windows 7 time. I set up Windows 7 with the usual (Firefox, Notepad2, some Ninite stuff, Graphics Drivers) and bob was my uncle. In the middle of all the installations and updates I did restart multiple times, but all the while my OS X was happily disconnected.
I connected my OS X drive to complete my triple-boot with Chimera and 10.7.3 and 12.04 worked perfectly. I tried booting into my Windows 7 partition and it gave me the BOOTMGR is missing error. "Fine" I thought.
I disconnected my OS X drive, popped the Win7 install disc in, ran the 3 commands that included /FixMbr and /RebuildBcd and restarted (with the OS X drive still disconnected). It worked. Connected the OS X drive and tried to boot into Windows 7 through Chimera, and I was greeted with the BOOTMGR is missing error again.
I should mention that booting to sdb using the BIOS boots straight into Windows 7 with no issues - no Grub in between.
Help would be appreciated.
