My dell optiplex 740 will open windows ,so before this happened,i install windows 7 home premium instead of windows 7 professional.When it didn't install properly,my windows will not open after i restart my PC it keeps saying The computer restart unexpectedly or encountered an error.Windows installation cannot proceed.To install windows,click "OK"to restart the computer,and then restart the installation.this message keeps repeating itself every time i boot my pc up.I try to reset my PC factory settings,but it wouldn't work,do i need to buy a Dell recovery disk to get my PC running?
Sounds like a faulty hard drive is the cause - F12 at powerup. Boot to the Dell diagnostics and run an extended test (not just the quick test) on the hard drive -- you'll likely find it fails, in which case - replace the drive and reload.
when i press F12, i get a pop up menu saying Boot Device Menu: 1.Normal. 2.Diskkette Drive 3. Hard Drive 4. CD/DVD=RW Drive
5.System Setup. 6.Hard Drive Diagnostics 7. Boot Utility Partition. When i did the .Hard Drive Diagnostics, all it read is IDE Drive Diagnostics,it said SATA 1ST Master - PASS
SATA 2ND MASTER - Not supported
Test complete,Press(Enter to Reboot).does this mean i have to buy another hard drive with Dell recovery disk?
So what this mean? Do I have to buy another hard drive plus Dell recovery disk?
You have to install F6 Mass storage drivers because the onboard storage is not native to windows.
Otherwise Sata Operation must NOT BE AHCI must be ATA.
Encountered a problem aka STOP 7B
AHCI = STOP 0x0000007B INACCESSABLE_BOOT_DEVICE
You MUST install F6 drivers at the time of OS install from floppy for AHCI.
Or Install ATA /Combination/Legacy and run the patch.
You MUST install in ATA /COMBINATION/ LEGACY MODE.
After you use the BIOS setup of a Windows 7-based computer or a Windows Vista-based computer to change the Serial Advanced Technology Attachment (SATA) mode of the boot drive to use either the Advanced Host Controller Interface (AHCI) specification or redundant array of independent disks (RAID) features, you receive the following error message when the computer is restarted:
STOP 0x0000007B INACCESSABLE_BOOT_DEVICE
Error message occurs after you change the SATA mode to AHCI
This issue occurs if the disk driver in Windows 7 or Windows Vista is disabled.
This driver must be enabled before you change the SATA/RAID mode of the boot drive.
