I had actually 4 OS mounted in my system. Just 2 of them were starting as well as mistake 0xc0000428 was presenting when I attempted too right into the various other 2.

But previously I really did not have any kind of issue when I mounted the boot loader on DISK 0 which was a 80 GB HDD. I changed the modifications. Hoila! It functioned just. I did not also carry out any type of commands.

If F8 jobs, after that you can utilize the “Last Known Good Configuration” alternative. and also “ Safe Mode with Command Prompt” to make essential adjustments.
