pLaYeR45 The problem is if i try to mount and clean the hdd. The laptop starts to make clicking noise and becomes very slow and unresponsive.
That clicking noise is the hard drive's death rattle.
Axios I dont know your boot sequence either if that disk is first in list might be hanging it.
@pLaYeR45 Consider going back into your BIOS, look for a BIOS entry labeled "Boot Sequence" or similar, and look to see what boot loaders are present.
Solus boot loader is normally called "Linux Boot Manager", Windows boot loader is normally called "Windows Boot Manager", and other Linux builds (the ones that use Grub) are called by different names (for example, on my computer, Ubuntu Budgie's bootloader is called "Ubuntu").
If you can identify the Solus boot loader (simple if it is named "Linux Boot Manager"), try two things: (1) move the Solus boot loader to the top of the boot sequence list, and (2) if your BIOS permits, see if you can disable/remove all the other boot loaders from the list. Either might move the Hitachi hard drive out of the boot path.
