Bug Description
There's a well know issue that BIOS raid is not be natively recognized by Ubuntu.
So, we used to change it AHCI mode in BIOS setting before installation.
But, if you have a windows machine which already created raid by BIOS, then only change it to AHCI mode in BIOS setting might not solve your problem. And installer might not recognize the disk.
Because of BIOS wrote some header on your disk during creating raid.
So, the storage is actually be treated as a disk which not existed partition table.
There're 2 workarounds can be done to fix it.
- re-create the partition table on the target disk.
- destroy raid by BIOS setting.
I create this ticket is to find some better solution guild people do that to improve user experience.

TBH I'd rather Linux does nothing in this case if I voluntarily changed the BIOS setting, or created RAID under Windows. Just don't destroy my data. At most, Linux kernel may print some warnings for this, which we already have.
