It is very common for multi-system computers to use the GRUB bootloader or its big brother GRUB2. And it often happens that experimenting with the bootloader or installing another operating system on a PC knocks down the GRUB / GRUB2 settings or, even worse, completely removes it. In this article, we will look at one of the cures for recovering the GRUB or GRUB2 bootloader — this is the Rescatux recovery disk. You can also reset your Windows password with Rescatux and much more.
What is Rescatux?
Rescatux is a recovery disk image (Live CD With linux), distributed free of charge, which contains tools for administering and restoring operating systems, disks, bootloader GRUB/GRUB2.

To create a recovery disk, you need to download ISO image Rescatux or Super Grub2 Disk. Write this image to CD (for example, using a free program CDBurnerXP in Windows) or USB (for example, using a free program UNetbootin).

Booting the computer from the Rescatux recovery disk
After creating a recovery disk, insert it into your computer, enable BIOS to boot from this disk, and boot your computer.
On the first screen you’ll see, you’ll be able to choose the boot option: 32-bit computer, 64-bit computer, or auto-detect. Here you can only download Super Grub2 Disk, which was mentioned above. To download, leave the first item — Rescatux autodetect.
