Windows 7: Cannot boot from HDDs after Power Outage

18 Dec 2010   #21

Windows 7 Ultimate x64

Well, I'm having a bit more problems :/ In the BIOs i switched it to ACHI mode and then back to disabled.. since then there has been issues. Windows 7 was no longer recognized and I couldn't get it to go back by doing what I did before. I got the drivers from gigabytes site and when I choose the drivers they're all JMicron. The driver didn't matter much. I tried all of them. Windows still isn't recognized. Startup repair said there wasn't a partition with Windows.

Though I ran the minitool partition wizard and it recognizes it and all the data in my HD. So is the data safe? If I were to just get a new HD and install windows on it, could I just use my WDC for storage or just transfer the files to my new HD and then just swipe it clean with a new partition? I like that the data is there and I'd get a new HD rather than doing a clean install... unless there is a way to just fix this.

I believe you have to follow certain steps to enable AHCI for an already-installed OS:
AHCI : Enable in Windows 7 / Vista

If you can see your data in PW, then you should be able to copy it out using the Install DVD or REpair CD using this method: Copy & Paste - in Windows Recovery Console

Yeah, the data shows up in WinRe so I'll just copy and paste it when I get my new hard drive.

Alright. I got a big a new HDD and a SSD. Installed Windows on the SSD and all my data is unharmed.. It's all there.. So everything is all good... Just gotta piece everything together again.
