Hello, how are you?
My name is Paloma B., I am very happy to be able to try to help you in the best possible way.
This is an open community, whenever you need you can share the problem so that possible repairs are suggested.
Could you give more information about the problem, please?
Please share a screenshot of your computer's Disk Manager?
Do you have more than 1 disk, or multiple partitions on the same disk?
Disks appear normally in the BIOS?
