thin bootable checkdisk

I have a friend in europe who only has access to a dialup connection and hes getting the unmountable boot volume, Besides getting him to spend hours of downloading a windows iso is their a thin bootable version that will allow him to perform a checkdisk? I know that sometime if i use a password reset disk from linux it will force a checkdisk on boot but sometimes this error requires a complete checkdisk.

You can download a tiny iso to boot from and run a chkdsk.

There are a number of boot cd's out there, like bartpe...and others. But not allowed to mention some here.

Hi There,

I wouldn't bother 99.9% chance that there is a corrupt sector or cluster of sectors on the HDD... Where the MBR is kept.

I would suggest replacing the HDD....

But answer to your question there are several Boot Disks that you can download to fix your problem.
I suggest looking here

If you go to the DOS tools section you will find the manufacturer HDD testing software that is compact and bootable.
10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

I would also check the HDD using the manufacturer's utilities. However, this error occurs with much more than just dying hard drives. Bad drivers, improper shutdowns, etc. can cause data to be written incorrectly or only partially written to the HDD. Checking the HDD will help determine if that's the cause.

i have encountered this error where the physical hard drive needs replaced but the computer is a notebook and usually encounters this problem during hibernation.
We get about 5+ a week that pass drive test and just need a checkfisk performed.
Didnt even think of thanks
How can you be sure 99.9 the drive is defective Kavo? I've dealt with a few unmountable boot volumes from clients who experienced thunderstorms/power outage equaling improper shutdown, causing file corruption which chkdsk /f fixed.

Run chkdsk /f from command line with the boot cd. Chkdsk /f will tell you if there are bad sectors and how many. If bad sectors, chkdsk /f will mark then into the bad sector file not to use and you have a chance of booting your computer. Pull your files off, backup your pst if any and search for new drive.
If your friend has a floppy drive, they can download NTFS4DOS Personal and create a bootable floppy that runs a Checkdisk program.

Here's the program:

Here's the manual:

Chapters 4.1.3 (Creating a Boot Diskette), and 6.2 (Check and Repair Hard Drive) are the main instructions they'll need to follow.

If they don't have a floppy drive, NTFS4DOS is also included on the Ultimate Boot CD (UBCD), which they could download from here:
The Self-extracting 7Zip EXE is only 87MB, and would extract the full ISO file, so it should save time over downloading a Windows ISO, and has a lot of other useful tools like disc diagnostics and such.

BTW, if your friend needs a program to burn the ISO to CD, I recommend BurnCDCC, which is under 100KB and runs as standalone EXE that doesn't require installation:
