CREATE A WINDOWS 7 SYSTEM REPAIR DISC!
Let me tell you a story too from 2 nights ago.
It was a dark but not stormy night, I was running clonezilla on my C drive to clone to a new 1TB F1 hdd but I decided to use the 1TB on something else later so cloned that to a 500GB Western Digital Black edition.
All was well but I realised that I now had 3x drives with the same OS, same drive signature and same boot loader so needed to cleanse the older 2 partitions and didn’t want to do it in Windows incase during boot I got complaints.
So I booted up using the XP SP3 CD as I knew I could delete partitions from that no problems.
Seems XP does not like playing ball with partitions on system disks because I removed the parts fine but it also removed the boot loader on the newly cloned drive!
I booted up with the 7 Repair disc I created the night before and it detected that the drive had a missing boot loader and asked if I wanted it to repair it so I did that and all was well.
Saved me a whole night of reinstalling that did and now I also have a system vhd image saved on external disk just incase I need to boot again and there’s something worse than missing boot loader
