hello,
OK i scan with FRST and i have attached may it could be some help

also attach FRST Additions.txt log

From the reatogo desktop select command prompt
At the prompt type the following and enter

chkdsk c: /r

Then try a normal boot

@essexboy tried that but not working

Could you please try attaching the other logs? Thank you.

ATTENTION: Software hive is missing. this is the problem…

Could you go to this thread and run the OTLPE boot option https://forum.avast.com/index.php?topic=53253.0 From If you cannot Boot the computer

i scan again but can get additions.txt but only frst.txt even after additions txt ticked in frst. here i attached

Your c drive is not visible…

From the reatogo desktop select command prompt and type in the following

chkdsk c: /r

If this should fail then I am afraid you are looking at a re-install

i tried this " chkdsk c: /r" but still not working

Unfortunately there is nothing I can do. From the Reatogo desktop are you able to see the files on your C drive. If so I would suggest you backup what you need and re-install windows

nope cant see drive c in Reatogo desktop , so remaining option is to reinstall .there is very important data that i need,i think i will wait a few days or weeks maybe somebody will come with something or at least on how to get the data then i can reinstall, thank you so much for your kind help!

If the drive is not visible then I do not feel you will be able to recover the data
