Boot loader drive failed. OS drive ok but no boot loader. Urgent.

post #1 of 8
Thread Starter 
Edit: Problem fixed, thanks for looking.


Posting from iPod

Had a raptor that was my system drive (contained boot loader) which pointed to a windows install on a 640gb drive. So BIOS handed off to raptor which pointed to c:\\windows on the 640. OS is windows 7

Anyway I accidentally killed the raptor. 640gb with windows OS files is ok, but since it contains no boot loader it can't boot - just freezes after bios screen when windows would normally boot

I have the windows 7 DVD. Automatic fix failed. Can access command prompt or windows install

How do I rebuild boot loader so that 640 drive can point to c:\\windows and boot itself?

To clarify raptor originally had xp. When I installed win7 on new drive I set up a dual boot but raptor kept the boot loader/os selector.

Bootrec.exe options
The Bootrec.exe tool supports the following options. Use the option that is appropriate for your situation.

Note If rebuilding the BCD does not resolve the startup issue, you can export and delete the BCD, and then run this option again. By doing this, you make sure that the BCD is completely rebuilt. To do this, type the following commands at the Windows RE command prompt:

* bcdedit /export C:\\BCD_Backup
* c:
* cd boot
* attrib bcd -s -h -r
* ren c:\\boot\\bcd bcd.old
* bootrec /RebuildBcd

/FixMbr
The /FixMbr option writes a Windows 7 or Windows Vista-compatible MBR to the system partition. This option does not overwrite the existing partition table. Use this option when you must resolve MBR corruption issues, or when you have to remove non-standard code from the MBR.
/FixBoot
The /FixBoot option writes a new boot sector to the system partition by using a boot sector that is compatible with Windows Vista or Windows 7. Use this option if one of the following conditions is true:

* The boot sector has been replaced with a non-standard Windows Vista or Windows 7 boot sector.
* The boot sector is damaged.
* An earlier Windows operating system has been installed after Windows Vista or Windows 7 was installed. In this scenario, the computer starts by using Windows NT Loader (NTLDR) instead of Windows Boot Manager (Bootmgr.exe).

/ScanOs
The /ScanOs option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista or Windows 7 installations that the Boot Manager menu does not list.
/RebuildBcd
The /RebuildBcd option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, this option lets you select the installations that you want to add to the BCD store. Use this option when you must completely rebuild the BCD.

Posting from the computer now - the fixboot thing worked. Thanks for the prompt help.

Windows is not bugging me about not being validated, which it was before. Not sure what the deal with that is.

I actually ended up doing everything you said (bootrec /fixmbr bootrec /fixboot bootrec /rebuildBCD.) Not sure which one actually did the job, but no harm in trying them all I think.
