I have a HP Envy 15t. Just got a BSOD when I tried to boot up my laptop today with the following message: "Your PC needs to be repaired. The operating system couldnt be located because the kernel is missing or contains errors. File:\Windows\system32\ntoskrnl.exe. Error code: 0x0000185. I get the same message when I try booting into safe mode as well. I tried a system quick test and it failed. The results were: Hard Drive Short DST Check: failed. Failure ID: PSGF7K-77P8G9-MFPV7F-60QQ03. I have a windows 8.1 disk that I use for my desktop, should I use it to try and repair my laptop? I don't know how to go on from here. I have a lot of files on my laptop that i'd rather not lose. If I have to replace the HDD, thats honestly fine with me, but is there any way I can extract the files on my laptop?
