A while back..I used my netbook and booted into Linux Mint16..it seemed too slow than usual until it hanged. I rebooted to Windows 7 then fell asleep. When I woke up, it was on standby at the login screen..I logged on and while waiting for everything to loadup, it again hanged. I restarted the pc and it showed "error: unknown filesystem grub rescue grub>"..I restarted a few time till I get to a working grub and booted on W7 which prompted repair that lasted almost 2hours..
At the loading screening suddenly an error saying "windowsconsole.msc is missing and needs to install that program something like that"..then when it got past the loading screen, it hanged while loading desktop.

I used this computer a day before and it was working fine both on Linux and Windows..please help me fix this, I hope it's just OS problem..there's too many files there to be lost.

Try booting to a live copy of linux and take a look at your drives. If you can't just mount them normally there's a program in Mint called Disks, open that and see if you can spot everything. You can even turn off windows sleep mode there. There's another program named testdisk that will help you recover data if all else fails.

new update..I have Windows 8 boot drive for repair..tried system restore,refresh and repair didn't work..then I used commandprompt for bootrec etc. Now, I'm having disk read error..and if I try to boot with Windows 8 installer, I get 0x0000098 error. I also put it in my desktop but it won't show with other drives..it gets detected in the BIOS though.

I tried that..it found only 1block or sector, I can't remember. Then at a point in stage3 it freezed, I restarted, that's when 0x0000098 happened. Saying pc needs repair I have to use intallation disc.

Please, use a linux live DVD or better still USB. Backup your files to another disk drive. If the live Linux can't open them try with testdisk http://www.cgsecurity.org/wiki/TestDisk

Skittle has warned you of a possible hard drive failure and that very well may be the problem and the longer you mess with it the less chance of recovery.

After you backup the essential then we can proceed to examine your options.

Yes any will do. Install it on a flash and boot to it.

If you can open your partitions great. Copy to a different drive your valuable files. This would also indicate that the windows repair removed your GRUB bootloader and it needs to be repaired. This is easily accomplished by installing boot-repair https://help.ubuntu.com/community/Boot-Repair and let it run the default repair. You should then have access to at least linux and run disk diagnosis tests to see if your hard drive is failing.

If you can't open the partitions then you need to go the testdisk http://www.cgsecurity.org/wiki/TestDisk route to recover your lost files.
 
Didnt you read your own error message? Its pretty explicit in this error message.
Failed to mount '/dev/sda3': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important!
Like i said earlier in thread. Boot a Windows disk and run the chkdsk program! You cannot fix this with Linux.

i've just gave up on my files and cleaned all partition..then was able to install windows 8.1, boot to it smoothly, and used it for few hours without any hiccups..although warning keeps showing on post, smart predicted hard drive failure, and windows also shows hard drive failure warning once in a while. scanned the drive with hdtune at about 80 percent and found 11 damaged blocks. i know it could just break down completely anytime, just hope it would last a bit longer. i'd be using it just for internet browsing for the mean time.
