First post here, but as with most members Google led me here because I'm having some PC issues so I thought I'd get some advice here if no-one minds. :confused:
I have a Dell Vostro PC - it has 2 SATA HDDs and a DVD Drive. The original default OS was Vista Home Premium. Recently I wanted to try out Windows 7 Ultimate so I decided to set up a secondary partition on my primary HDD to install Win 7 there to test before taking the plunge with a full upgrade. This worked fine - I created the partition in Vista, defined it as the Y drive and successfully installed Windows 7 there no issue. All was well and I could dual boot both, although I have to say I mainly used the Vista install with the occasional Win 7 test.
However, in the last 24 hours things have gone very wrong and now neither installation works. Strangely nothing has been installed or changed on the machine yesterday to trigger this.
If I attempt to boot into Vista I get a Winload.exe error with error code 0xc0000428 telling me that winload.exe is missing or corrupt. Last night, I managed to get past this error once and into safe mode to perform a virus check, but since then it constantly cycles with the same error when booting or attempting to access advanced boot options.
If I attempt to boot into Windows 7, I get a bar saying Windows files loading and then the machine reboots without loading further. Same again if I try to access Advanced Boot Options for Windows 7.
Things I've tried so far are:
1. Booted from Vista Install disk and peformed a start-up repair - didn't resolve issue.
2. Booted from Vista Install disk and run a chkdsk /f - didn't resolve issue.
3. Booted from Vista Install disk and from cmd prompt copied winload.exe back to /system32 from /system32/boot - didn't resolve issue.
4. Booted from Windows 7 Install disk and performed a start-up repair - didn't resolve issue.
Now having read thru some of the other info out there I'm aware they're more things that I can try revolving around bcdedit.exe and bootrec.exe, but as neither windows install is currently working I'm not sure in what order to fix and which I should try first! I'd rather do a repair install for Vista as a last resort, but that is also an option if needed. I also have a sneaky suspicion this maybe hardware related, but I'd like to get the machine backup and running before I make any HW changes.
Thanks in advance for all help and advice. :thumbsup:
