Thread: grub rescue: error unknown filesystem TOUGH CASE, please help ...

-

hello,

after laptop system crush (which caused hard restart), ubuntu linux not booting, showing now:

error: uknown filesystem
grub rescue>

solutions tried:

1st solution)i've read lot similar problems , i've tried work grub rescue console:
grub rescue>ls
(hd0) (hd0,msdos5) (hd0) (hd0,msdos1)
grub rescue>ls (hd0,msdos5)
error: uknown filesystem
grub rescue>ls (hd0,msdos1)
error: uknown filesystem
so, can't list/find linux filesystem ,,,

2nd solution)
after all, decide try boot repair, i've installed on ubuntu live usb, there no "recommended repair" button , there no "advanced options". there 1 button "create bootinfo summary" - i've created one, link http://paste.ubuntu.com/5609223/.
tried bootrepair on latest ubuntu , on linux secure remix, both live editions baked on usb - same result, boot repair not working.
os-uninstaller on linux secure remix states there not found/installed os.

log boot repair:
http://paste.ubuntu.com/5609223/

tried same linux secure remix on different pc , @ least there button "recommended repair". think problem in hdd or mbr .. don't know..


out of options... please, help!

thank you!!!

it seems need reinstall.

a week ago in premiere pro cs6 world. one day updated windows, next day few .mp4 video files opened in premiere pro, played fine well, except fact display has green (sometimes multicolour, solid green block) bars in lower third of screen. see screenshot below.   these same files open/display fine in after effects, photoshop , vlc- , quicktime players. i'd read fromyears ago windows updates causing this, removed 1 of therecent kb's no avail. i did install adobemediaencodertrial_64-6.0.3-mul-adobeupdate and dynamiclinkmediaserverretail-1.0.1-mul-adobeupdate and reverted quicktime 7.6 but nothing makes difference.   in end, formatted c:\, reinstalled windows 7 ultimate 64bit , downloaded/installed 260 updates , reinstalled cs6 (and aforementioned ame , dlms updates , qt7.6) it's still same problem.   also tried exporting (part of) 1 of these files, see if wasn't display problem: exported file same properties original has green bars.   what else can do?   thanks in advanc
