Reinstall Remix OS without losing data

[AcidRian0]

I have setup Remix OS as dual boot with windows 7

It was working fine till a few days ago

But now when I select Remix OS from Boot Menu

It shows \ubnldr.mbr

File corrupt or Missing

Is there any way to Re-Install Remix OS without losing any data

Or is there any way to fix this issue

 

[Lenn1]

to fix

this is a bug that happens in repartitioning the Hard Drive ... to fix just use open the command prompt as adm and type:
chkdsk / f d:

"d:" is where the remixOS is installed
sorry for the bad english

Chkdsk d: /f enter
Where d: is your remix drive
And make sure menu.lst is copied in the d :
