My Toshiba Satellite Pro running Win 8.1 Pro can’t boot – or rather it keeps booting and going into diagnostics and just stays ‘diagnosing system/hard disk’ forever. I ran testdisk on the drive and the first option that shows up in Analyze is EFI GPT. If I choose that option I get a list of partitions – no duplicates, no overlaps as far as start/end – all marked P. The partitions are:
1 P unknown
2 P EFI
3 P MS Reserved
4 P MS Data
5 P Unknown
If I do a deeper search from there I see all 5 partitions but now they are marked as follows:
1 P MS DATA [System]
2 P MS Data [No Name]
3 P MS Data (nothing in the far right column)
4 P MS Data [T1….] (looks like Toshiba HDD ID)
5 P Unknown [Recovery]
I did yet a deeper search at this point and got all kinds of errors about:cylinder mismatches, sectors per track mismatches with one or another of bracketed [FAT], [EFISECTOR],[HD], [BOOT] after each line indicating the mismatch.
In any case when I chose to see the files on the various partitions with the P command, I once again could see all my files on partition 4.
I then ran testdisk again and chose the Intel option.
The first screen showed one partition – P EFI GPT
And a message:
Bad ending head – CHS and LBA don’t match.
No partition is bootable.
I did a deeper search and I again got 5 partitions but this time they were all marked D in the far left column. No overlaps
The partitions were as follows:
D HPFS NTFS …. [SYSTEM}
D FAT 32 [NO NAME]
D HPFS NTFS (nothing in the far right column)
D HPFS NTFS [T1….] (looks like Toshiba HDD ID)
D HPFS NTFS [RECOVERY]
Once again partition 4 was the one that listed all my files when I browsed with the P command.
A few more points I should mention.
1) The computer started acting flaky after a dirty shutdown
2) After that dirty shutdown I created two restore points. When I first started to troubleshoot this problem I was able to get into the Toshiba recovery screen but when I asked to restore from the restore points it indicated I had none.
3) This system did not come with media – it has some kind of recovery partition built in for these kinds of problems. In any case I can not get into the system as it just keeps ‘diagnosing’ – so the zero key or F12 or F8 don’t work.
4) I did not add a partition since I purchased this laptop so as far as I know it only had a C drive – I can’t recall if there was an additional drive letter that showed up in Explorer or Disk Manager but I can’t exclude the possibility that there was indeed one there.
So given the above what is my next step. Partition 4 looks like the correct one and I will back it up and ghost before doing anything. But as far as trying to get this bootable again what should I be doing? I am not sure what partition to mark what. How non-destructive is testdisk for this partition/boot sector tweaking – what are my go back options other than the backing up/Ghosting right in testdisk itself.
Also when the program asks to create a log where is that log going to be created?
Thanks in advance for any assistance with this.
