How to uninstall Mandriva and restore Windows 7 Bootloader?
Use windows 7 boot disk, enter rescue mode, type bootrec.exe /Fixmbr ? Any suggestion? |
You seem to have answered your own question, I think... Or are you looking for a different solution?
You could try to use a GNU/Linux live CD, install ms-sys (many distributions have this in their repositories), and write a new Windows 7 boot sector. For example, you can run `ms-sys --mbr7 /dev/sdX`, where X is the letter of the drive on which you have Windows installed (if you're unsure of this, run `fdisk -l` and look for an NTFS partition that you recognize). |
for reinstalling Microsoft and the win7 bootloader
search the Microsoft web site they have the instructions there ( it is there os after all) the OLD instructions for xp and the "newer" ones for vista DO NOT APPLY ,or work for windows7 |
For windows 7, after bootrec.exe /fixmbr, its bootloader still unrestored.
have to go back to the screen, click Repair, and windows will do something and restored. |

did you reformat the mbr ?
microsoft can not read NON Microsoft partition formats i am willing to bet that Mandriva formatted it to ext3 |

It's the boot code that is OS-specific (or more accurately, boot loader-specific); Windows OSes each have their own boot code, which bootstraps the OS and runs the NTLDR process on the partition marked bootable in the MBR partition table. Mandriva wrote the boot code for either GRUB or LILO (whichever you used) into the MBR; that code would load up the kernel with your initramfs, which in turn bootstraps your system and eventually passes control off to init. |
