I have a Windows 7 x64 installed on a single disk with 4 partitions:
- The default 100MB invisible boot partition
- 150GB system partition C:
- 2x 850GB partitions D: and E:.
After experimenting with another disk (an SSD planned to be used as a working disk for video editing, but that's another sad story), the drive letters got messed up. The invisible 100MB partition took the C: letter, so all the other partitions moved for one letter, preventing a normal boot!
The Startup Repair that keeps popping up is failing to fix the problem by itself. Using the DISKPART command from the Advanced mode I removed the letter from the 100MB partition and reassigned the other partitions to their original letters, but on the first boot, the 100MB partition reappears, messing up everything!
Please, guys, is there a solutuon that does not involve a complete OS reinstallation?
