Windows 7: Dual Boot - XP Install Not Showing All Windows 7 Partitions

30 Mar 2012   #11

Windows 7

Unfortunately, it still wont go into Win7 even with the other drive unplugged, continues the boot loop. I have tried the Win7 repair using the HP Recovery console. The Win7 repair details looks like it says something like NO_OS as a reason.

I have tried using the commands
bootrec /FixMbr
bootrec /FixBoot
bootrec /RebuildBcd - which give the error: requested system device cannot be found

I am thinking of using the HP Restore and just go back to the original HP install. Since this is going to a development system, there will be some programs I will have to install, but I do not think a major hassle. Then we will just use the HP boot manager.

The XP-era bootrec commands are all automated in Win7 Startup Repair which often has other repairs it needs to run in tandem. Make sure the Win7 partition or its 100mb System Reserved partition are marked Active first. Then run Startup Repair - Run 3 Separate Times

However if GRUB is on the Win7 HD it can corrupt it beyond repair.

I would consider clean reinstalling as do most tech enthusiasts, especially because HP has the worst load of preinstalled crapware in the industry. Here are the steps: Clean Reinstall - Factory OEM Windows 7

You can copy out your files to external using Win7 DVD or System Repair Disk using this method: Copy & Paste - in Windows Recovery Console or Paragon rescue disk to recover data
