Good evening,
I'm trying to help a friend; I'm usually okay with computers... but this time I'm stuck. Here’s the problem: her computer starts up but a message saying "AHCI Option ROM BIOS Revision etc port 1_" appears. She wants to format it; I launched a bootable DVD for Windows 10 installation, but when I reached the drive, it says "Drive 0 unallocated space" 0.0 MB and it's impossible to delete or format, everything is greyed out except for new, but when I select it, I receive a message saying impossible 0 MB. I also can't access the BIOS on startup by pressing F2 or Delete, the same initial message keeps showing up. Her computer is an ACER Aspire X3200.
I'm afraid her hard drive might be physically damaged. There was an online procedure to check this, but the computer won't open a DOS window by pressing Shift+F10 when I'm on the disk selection display.
Thanks in advance for your replies.

Hello.

If the space is considered Unallocated, it simply means it is not formatted.
You will need to do this under the DISKPART command, do you have the USB stick or the Windows installation DVD?

It's not the space that is unallocated, it's the size of the disk
otherwise he would just have to click new and create the main partition to install Windows.

it says "Drive 0 unallocated space" 0.0 MB and it's impossible to delete, to format everything is greyed out except new

Good evening,
thank you for your response. If I understand correctly, even though "formatted" is greyed out and "new" is not possible, I can do it another way with diskpart, but I'm not very familiar with command prompt (I suppose it's a command prompt). How should I proceed? Thank you.
