I have an Asus motherboard P6T Deluxe V2. Due to an inverter power break down my APC UPS also tripped and caused the PC to shut down. After that when I booted the PC, an error used to come that cannot find floppy drive press F1 to resume. Pressing that button brought me back to the old familiar multiple boot menu of XP, Vista and windows Seven. Since this was annoying I decided to get rid of it by upgrading the bios from Version 1108 to Version 1202.
When the bios was upgraded the floppy disk error went but for the first time in my computer life I found upgrading a bios to cause problems. I could manage to boot to Windows XP in safe mode with networkinng but could not boot either to Vista or to Seven. From Windows XP I managed to go to the Asus Website and managed to revert back to the old bios 1108 by flashing it. After that I could go to Windows XP but still could not access Vista & Seven. The BCD boot loader was either missing or had become corrupted. I tried to repair Windows Seven and Vista by their discs but failed to. I had Acronis images of all the three Windows. The latest was of Windows Seven being of Feb 2012 but even that was old because I used Seven the most frequently. i therefore decided to restore Vista from a Nov 2011 Acronis image. But even after restoraton of Windows Vista Nov 2011 I still could not boot either to Vista or to Seven. I tried the Windows Repair from Windows vista Disk but it seems that the BCD is still corrupt or missing I can only boot to Windows XP but not to Vista nor to Seven. So how to bring back the boot of Windows Seven & Windows Seven
