I started my laptop (Acer S7-391) 2 days back and it was fine, did some windows updates. I was able to login after reboot, then I left my desk for a few minutes...when I came back I see the black screen with "No bootable device" message!!!
I did some research and tried a few things, sadly it is still NOT booting...
Please let me know...
1) what else can be done to have it running again, without having to reinstall windows, if possible
which boot mode should be set? which partition should be active?
2) (if there's no way to get the existing install working again) steps for clean install & configurations...if that is still an option...not an ssd issue?
>should I clean&re-partition the drives? how should it be done?
>settings in BIOS? boot mode?
>It came with windows 8, then I did the free upgrade to windows 10. I have the old windows 8 backup image. Should I restore 8, then upgrade to 10? or reset with windows 10?...If I can still get windows 10, read that free upgrade to windows 10 is no longer
available...
Here's what I tried...
>change boot mode from UEFI to Legacy BIOS
--still unable to boot
CTRL+i showing disk/volume information
Volume0 RAID0(Stripe) Status Normal Bootable Yes
>boot from USB and repair
--Failed, windows is unable to repair
>download and install latest BIOS firmaware from acer's support site (BIOS 2.18)
--Now a different error display
Windows Boot Manager showing
"Windows failed to start. A recent hardware or software change might be the cause......"
>boot from USB and repair
--Failed, windows is unable to repair
>then I found and can access my original C drive, somehow it became G drive...all files seem to be there
>diskpart>list volume showing
Volume 0 C Recovery NTFS 400MB <-- this is ACTIVE
Volume 1 F ESP FAT32 300MB
Volume 2 G Acer NTFS 222GB
Volume 3 H Push Button FAT32 15GB
(D&E being removable drives)
Recovery drive containing OEM, Recovery, Temp dir
ESP drive containing EFI dir
>chkdsk /f
--found and corrected many issues "Windows has made corrections to the file system."
--run with /r seems to be stuck at stage4 50% for more than 1 hr...read that it is unnecessary to run with /r on SSD so I killed it
>changing boot mode back to UEFI, showing a different error message
blue message box "Windows Boot Manager boot failed"
>making G: (the original drive with windows installation) active -- no luck UEFI or Legacy mode
>sfc /scannow
--"Windows Resource Protection found corrupt files and successfully repaired them."
still unable to boot
>bootrec /RebuildBcd /fixMbr /fixboot
--completed successfully, still not booting...
--error "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system."
(followed steps here http://www.thewindowsclub.com/the-drive-where-windows-is-installed-is-locked)
Options when booting from recovery usb
>"Refresh your PC"
--error "The drive where Windows is installed is locked. Unlock the drive and try again."
>"Startup Repair"
--error "Startup Repair couldn't repair your PC"
>"System Restore"
--error "To use System Restore, you must specify which Windows installation to restore"
--tried running from cmd in offline mode, but all previously created restore points are gone...
>"System Image Recover"
--error "Windows cannot find a system image on this computer"
>"Reset your PC"
--error "Unable to reset your PC. A required drive partition is missing."
Appreciate your help!!
