Moderator, if you think this should be mnoved... Well, I think I did something wrong and now can't revert. I was asked to install Windows 10 in a dell note that has 1 SSD + 1 HDD. When booting, the note was showing something with the raid setup, asking to press CTRL+L. I did, but wrongly setup a raid 0 with the SSD + HDD. The problem now is that I cannot access more than 60Gb (the size of the SSD) whenever I try to install Windows 10. And the original Windows 7 is gone (along with the recovery partition) I tried entering the BIOS, but for some reason there is nothing about Raid. Tried every other forum I know and from what I could find, there is nothing I can do, execpt call Dell and buy new recovery CDs (because the owner of the note does not have them anymore), disassemble the note and disconnect the HDD or MOD the bios. Do you gurus here know anything else I coud do to break the raid (or display the hidden bios options) to revert the drives to AHCI?
