Types of SATA modes:
- IDE – Old, slower, it is simply a compatibility mode
- AHCI – AHCI stands for Advanced Host Controller Interface. It makes Native Command Queuing (NCQ) along with hot-plugging or hot swapping through SATA Serial-ATA host controllers possible. NCQ is one of the important features of AHCI for SSDs. SSDs can process requests faster than HDDs. It can process so fast that the SSD could end up waiting for work. NCQ allows the OS/controller to request up to 32 simultaneous requests at once. So you basically get more performance from your drive over older IDE mode.
- RAID – RAID stands for redundant array of independent disks, originally redundant array of inexpensive disks. It is a means by which your PC uses multiple disks as if they were one, either to increase performance, safeguard against disk failures, or both. RAID mode has all the advantages of AHCI mode. There are four main factors of a RAID setup: striping, which spreads data across multiple drives, mirroring, which copies the data to more than one disk, space efficiency, which is how much of the total space is available to use, and fault tolerance, which is a measure of how well protected the RAID array is against disk failure.
The issue with changing the SATA modes is they need to be enabled in the BIOS prior to OS installation; doing so after you have installed the OS will disable the PC. The reason why is Windows disables the drivers for the others that are not needed during installation. This tutorial will show you how to enable the different SATA modes after you have installed the OS.
Note: You may have to uninstall then reinstall any SATA drivers such as Intel RST or AMDs equivalent.
This method tricks the computer into thinking the computer it’s brand new and leads you through the setup again to create a new administrator account.
This guide should take only about five or ten minutes, but there is some music and you have to boot into single-user mode, so if your in a public place with inquisitive people bring headphones and try to be subtle.

It’s possible the Windows 7
ISO or DVD disc media that end-user possessed may be restricted to install a single edition or version of Windows 7 only. For example, a Windows 7 Professional media may not prompt option to select which edition of Windows 7 to install, and instead will install Windows 7 Professional edition. Likewise for Windows 7 Ultimate DVD ISO image or disc which may not have edition selection screen.
However, all DVD of Windows 7 does contains and able to install all and any version of Windows 7, from Windows 7 Starter, Home Basic, Home Premium, Professional to Ultimate edition. Actually, the ability to select the version or edition of Windows 7 during setup installation, or which edition that the setup will automatically install, lies with a small configuration file named ei.cfg on the Windows 7 DVD, disc media or ISO image.
Restoring from Restore partition without Ctrl+f11 nor restore disks.
Just to state first and foremost, this is not an issue I have. This is a preventative post for anyone that may ask down the line. (as I’ve seen it asked on multiple other forums.)
I had this issue with an inspiron 1720 I just got. It had an issue, so I installed vista from a Vista RTM disk. It didn’t fix the problem in the end, so I sent it into dell and got fixed, but I wanted to a fresh restore from the restore partition because on restarts, I’d get the blue screen of Death. Fun stuff right?
Well, Unknowingly, when I installed vista off of the cd, that removed the ctrl+F11 option from the dell. This is stated on many forums, and it seems that most answers to this issue is to format and install a fresh install from cd again, or call dell and get recovery disks. I figured “Heck, If I still have the restore partition, there is not reason why I can’t get it to restore with some effort.”
Some other people I’ve seen have just had viral attacks, or just want to sell their laptop and need a fresh install. This is for those people that need it. The answer to the question of what if Control and F11 don’t work.
