Hello All, Okay. About a week ago when I started up my computer, it went straight to Windows Error Screen with 2 options to either launch startup repair or start windows normally. Neither worked and when disabling system failure gave me the BSOD with the error message unmountable_boot_volume. Since then, nothing I have tried has worked. This system would not start in any mode (safe, last good configuration, etc). Then I created a Windows 7 recovery disk (both normally and using ISO file), booted from CDROM, and it would not run the recovery program, it would ask me for my keyboard input device, then a blank screen for hours. So I was told to change my BIOS settings from AHCI to IDE, which I did. It then ran Windows Recovery Disk and fixed startup errors, however still BSOD. So I did command prompt the next time using bootrec.exe and that did nothing. then I did CHKDSK for both C: and D: /F/R and it ran all of that and still has not fixed it. I have an Acer Laptop with Windows 7 32-bit. Any suggestions?
