Hi, folks!
I have MacBook Pro late 2006 (MACBOOK2,2) 15" 2,16 GHz. I had working Win7x64 installation on it unless I've tried to install Ubuntu into another partition, where Mac OS X 10.5 was located. Ubuntu installer killed my Win7 installation, though partition itself was not damaged. A message "Missing operating system" appears, when I try to select "Windows" icon in the Boot Manager.
Then I've tried to repair it with Linux gdisk utility, recreating the hybrid MBR. MBR was created, but gdisk assigned incorrect boundary for the very first EFI partition in the hybrid MBR, so now I see some new situation:
- Ubuntu is still running OK
- Win7 partition can be mounted within Linux OS
- a lot of lines appear when I select "Windows" drive icon in the Boot Manager, finished by "Press any key to command line mode". I press and "GRUB>" prompt appears. And this is definitely NOT the GRUB from Linux partition or EFI partition. It has different command set and (as I suspect) works in the CPU real mode, like DOS.
What is this GRUB? Any documentation? Any config file syntax? Whatever else? I can't find any info around the Net
The only thing I've discovered occasionally pressing Esc key, is that Boot menu appears (which was never seen before) with few items as
"Windows 7 / Vista / Server"
"Windows 7 / Vista / Server (no SLIC)"
"Debug (default)"
"Debug (legacy)"
"Windows NT / 2000 / XP"
"Loader help"
None of them work but "Loader help", which shows GRUB commands list, though it shows it so ugly, with lines truncated, so I can't see the right syntax. And there is no help on these commands (what they do, how to use them, etc.)
What is this loader? Is there any key combination to switch to this screen on normal power on?
I can provide screenshots if it's necessary.
Thank you.
