Cannot fix Windows 8's BCD, "fatal device hardware error"

Yesterday I turned on my laptop and it got stuck in an infinite Boot/bluescreen/automated repair/black screen loop. I booted into linux from a flash drive and performed memtest86 (everything ok there) and HDD SMART tests (100% ok). I then booted to Windows Recovery using Windows 8's bootable installation flash drive and tried to change the BCD records to make the system stop on the Bluescreen so I can jot down the error number, so I typed in




"bcdedit /set onetimeadvancedoptions on"




in the recovery console and I got a message saying





"the boot configuration data store could not be opened. The system
cannot find the file specified"




I've found a question on SU of someone with a similar problem (link) that recommended following the tips in this article. But as soon as I got to




"attrib -h -s C:\boot\BCD"





I got




Path not found - C:\boot




So I tried





cd C:/boot




And I got an uneasing message saying




The request failed due to a fatal device hardware error





I've tried CHKDSK with




chkdsk C: /F




which returned




A disk read error occuredc0000483




Insufficient disk space to fix the Usn Journal $J data stream.



Failed to transfer logged messages to the event log with status 50




I find it hard to believe that my SSD is heavily damaged, as under Linux I can read and manage files on it just fine.
Where should I go from now on?
