Hello,

I need some help with uninstaling Linux Mint using free DOS.
I bought a laptop, Lenovo G50, installed it from USB and everithing fine. I need to send back the laptop to the store, but they will accept it only without OS. It has to be only with the free DOS he came with. So, how can I unistall linux mint and keep the free dos? Linux mint is on /dev/sda5 and the free dos appears to be on /dev/sda1.

The laptop has a "Return to factory mode" button, but it doesn't bring it to the factory mode. When I press it, i have the following options: 1. Normal startup, 2. BIOS Setup, 3. Boot Menu, 4. System Recovery (this one goes to the boot menu, and let me choose between the installed OS)

Can someone help me uninstall Linux Mint and keep the free DOS?

Thank you!

You can't "uninstall" an operating system the way you can an application. Format the partition that Mint is on and delete it if you want.

That's what I want to do, to format that partition that mint is on, but I don't know how I can do this I tried fdisk and format, but freeDos doesn't recognise these commands.

You must have had a DVD/flash drive with Mint on it to install it to the hard drive. Get it out and boot from it. GParted is on it so you can use that to format/delete the partition.
