Q: Windows startup repair module: Result: failed. Error code = 0x45d This thread is locked from future replies

I have Win 7 x64 running on an MSI G41-M7 mobo, E2220 processor, 500G HDD, 4G RAM. It was running great until 4 days ago (11.04.24) when I shut it down in the PM. It installed a patch at that time. When I booted next morning, it worked for a while (5 minutes or so), then the mouse and keyboard were locked out, while the HDD was chattering away. I needed to use the machine, so I killed the power (mistake) and rebooted in safe mode. It did the same thing there (froze after a few minutes), and after a half hour it rebooted, but didn't find the boot drive. After powering down, I managed to get it to boot to safe mode and did a system restore to the pre-update state. After this, it booted fine normally, and I was able to use it all day. Then, on powering down, it installed an update (presumably the one I restored from), shut itself down, and I have not been able to boot it since. It'll start to boot, sit there with the little whirling donut for 20 or so minutes, attempt a re-boot, and won't find the boot drive. Startup repair gives the above message, even when run from the installation disk.





Chkdsk found no valid Windows partition. Bootrec found no valid Windows installation. I managed to boot with a ubantu boot disk and found the whole directory tree, so was able to recover my files. I'll just have to re-install everything from scratch. Not too bad...I just got that machine up and running a week prior, so didn't have a lot on it that wasn't on my old XP machine (which I'm using now).


I wasn't able to identify the update that installed just prior to the crash.
