Partition broken after Windows 10 blue screen

#1 Post by ferruccifran » 15 Jan 2019, 02:17

Hi everyone,

Yesteday (jan 2019) my laptop wouln't boot after Windows 10 blue screen.
Afterwards, I ran TestDisk 7.0 from a Ubuntu copied on a USB flash drive.
After selecting "Analize" I got this:

Code: Select all

Disk /dev/sda - 256 GB / 238 GiB - CHS 31130 255 63
Current partition structure:
     Partition                  Start        End    Size in sectors

 1 * Sys=F3               188905  16 46 413691 172  3 3611196876

Bad relative sector.
 2 * Sys=73               48857 194 55 276977 194 61 3664747807

Bad relative sector.
 3 * Sys=B3                8394 138 58 63867 120 19  891172573

Bad relative sector.
 4 * Sys=76               194118 224  5 449070 109 36 4095796667

Bad relative sector.
Only one partition must be bootable
Space conflict between the following two partitions
 3 * Sys=B3                8394 138 58 63867 120 19  891172573

However, after selecting "Quick Seach" it found nothing (it said: "No partition found or selected for recovery"). It then showed the option "Deeper Seach" but nothing in found either.

Note: the quick search and deeper search took a few minutes each (comparable duration). The hard drive is a solid state drive.

Before even using TestDisk I ran the Windows 10 troubleshoot disk and I executed the following commands without any luck:

Code: Select all

bootrec /FixMbr
bootrec /FixBoot
bootrec /ScanOs
bootrec /RebuildBcd
Note 2: gParted identifies the drive, and it says it is "unallocated".

Could someone help me out with this? I don't want to format and re-install.

Does PhotoRec recover some valid data (Recovered files will have generic filenames) or only random files ?

Hi there,

I have just run PhotoRec and it only recovered 5 files from the whole hard drive (random exe files and a couple of XML files). I chose the "no partition (whole disk)" option to run PhotoRec.

By the way, the laptop BIOS has a hard drive test utility (Lenovo Thinkpad Yoga S1 machine). I ran the test and it return PASS to all tests.
