# How to fix broken boot loader
|
||
|
||
OpenMandriva Lx uses grub2 bootloader, so grub2 commands would work.
|
||
The command to probe computer and write comprehensive grub2 menu is:
|
||
```
|
||
$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
|
||
```
|
||
In most circumstances this simpler command will work:
|
||
```
|
||
$ sudo update-grub2
|
||
```
|
||
Then to install the grub2 bootloader to the drive you wish to boot from:
|
||
```
|
||
$ sudo grub2-install /dev/xxx
|
||
```
|
||
Where you replace the “*xxx*” with the name of the drive you want to, or were booting OMLx from, like `sda` or if it is a nvme drive something like `nvme0n1`.
|
||
|
||
To do this obviously you need access to your OMLx system. It you do not have easy access you can try [Rescatux](https://sourceforge.net/p/rescatux/) or [Super Grub2 Disk](https://sourceforge.net/p/supergrub2/). For this task you may want to try Super Grub2 Disk first.
|
||
|
||
To find how your storage devices or drives are called, user can simply open KDE Partition Manager or from Konsole run the command:
|
||
```
|
||
$ sudo fdisk -l
|
||
```
|
||
<br>
|
||
|
||
### Additional information:
|
||
The commands `grub2-mkconfig` and `update-grub2` use the utility called ‘os-prober’ to probe the computer for other operating systems.
|
||
User can run this command independently to see if os-prober is correctly recognizing all other operating systems on users computer. Like this:
|
||
```
|
||
$ sudo os-prober
|
||
```
|
