When I try to install Windows XP it will not detect my hard drive which is visible in the bios. If any connected SATA HDD is not listed in the S-ATA drive list, check the SATA cables are properly connected to the connectors/ports, and that the SATA cable is in the master slot on the motherboard. Same issue here. However upon reboot the BIOS wont recognize the hard drives anymore (as in the BIOS itself not Windows). Either the IDE or SATA controller on the motherboard, or the controller board on the hard drive. Generally, if the hard drive is not recognized by the BIOS, you have a hardware failure. This isnt a new pc. When a SATA hard disk is connected to SATA connector, it should be detected at least at hardware BIOS level. My 2nd disk hard drive used to show up as disk 1 in the Disk Management and I even backed some files up to it. Cable connection is securely in place. However, drive does not appear in BIOS and I cannot get the laptop to detect it - so cannot proceed to do the OS install.

Conclusion. What could be the problem here ? Try a different SATA cable and see if the Hard Drive is detected. If possible, check the Hard Drive by connecting it to another computer. 6. Windows 10 has been so flaky, I never had these types of problems with Windows 7. My bios options are very limited, however i was able to use the bios to change the sata to ide.
