After 3 years, a sudden "Reboot and Select proper Boot device"
Edit: solution found (KB3133977 update clobbers ASUS motherboards using Secure Boot)
Hi folks, tearing my hair out over this one. Win7 Pro PC was operating fine earlier in the day, no hardware changes in almost a year. Power it up later in the day and I get Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key.
- There is a single DVD drive and only the Samsung SSD drive, neither has changed
- Both DVD and SSD show up in my BIOS. No matter how I arrange the SSD, I get the Reboot and Select proper Boot Device
- I can boot from my Win 7 Pro (64) install DVD. Since I know the DVD cables work, I swapped both the DVD's power and SATA cable to the SSD, no joy, so cables and SATA port seem fine.
- Doing Repair from my Install disk fails; I get "This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows." I moved a year ago, and my repair disk is missing.
- From cmd window via Install disk:
- I can access C: and see my files just fine
- Using bootrec:
- /scanos does detect c:\windows
- /fixmbr /fixboot /rebuildbcd will detect Windows and succeed across the board but still not correct the problem (see below)
- Using diskpart:
- I can see that my disk is GPT. GPT is new to me, I'm more familiar with MBR recovery. Does bootrec handle GPT too or is it just a relic now?
- 'detail disk' shows the Samsung, but with Boot Disk : No. That seems wrong?
- volume 1 c: shows up ok, 465GB, 202GB free
- I can't 'active' the partition, I get 'selected disk is not a fixed MBR disk". Makes sense if it is GPT, but I don't know what to do with GPT to mark a partition bootable
- Using chkdsk c:, no errors found
PC has been working fine leading up to this. I custom built it three years ago. Only thing of maybe interest is that a month or so ago I had tried to upgrade to Win 10, and had to abort due to an error (I can't recall specifics but it was some sort of a driver issue I didn't have time to sort out). The Windows install returned me to Win 7 without apparent problem. I'm not sure if this explains the 'Repair' error.
I've searched for help but I seem to be stuck:
- Fix the GPT - A technique I'm not familiar with, this is the first time I've dealt with a GPT and most of what I find on the net is MBR recovery advice
- "Repair 3 times" technique - But I can't repair, due to the Install disk's error above. How can I get around it?
I'd like to recover the data on the drive if possible. Thanks!
