I've been trying to uninstall windows 8 for past couple days now. From what I've gathered I need to change the boot mode from UEFI to CSM. Just one problem, my bios doesn't have that option! My BIOS is like none I've every seen before. Here's a pic of my BIOS under the System Configuration tab where the option to change from UEFI to CMS should be, based on the tutorials I've seen, but like I said nothing is there. This is really frustrating me. So I am just missing something, is there a work around for this, or am I just screwed?

Are you uninstalling from dual boot or trying to revert back to old windows version? Either way, you are not doing it right.

Please tell us, , , what computer? Did it come with Windows 8 pre-installed or did you install it yourself?
If you take off W8, then what are you going to use for an OS?

Too many questions and too few answers!!!

:cool:
PS: If I want to get rid of an OS, I just reformat the HD and it's GONE! Then I can install something else.
I've done that several times in just the last week.

My laptop came pre-installed with Windows 8.1 and I am trying to install Windows 7 over it

It's a Toshiba Satellite C55-A5104 that came with Windows 8.1 pre-installed. I have a copy of Windows 7 so that is what I will replace Windows 8 with. Wouldn't the problem with the BIOS still persist even after a HDD format? Like I said in order for Windows 7 to be installed over Windows 8, the boot mode in the BIOS needs to be changed from UEFI to CSM, but the option to change the boot mode does not appear in my BIOS. Also would I be able to use the Windows 8 recovery disks I made after the HDD is formatted with a new OS put on it?

I'm sorry, but I've run XP, 7, 8 and 8.1 on the same motherboard with the same old BIOS. So I don't understand your problem. Sorry!
Why don't you just install the Classic Shell and set up 8.1 to look and act like 7. That won't cost you anything.
Classic Shell 4.0.4 is FREE. And 8.1 really IS an advanced OS and runs faster than 7 on the same motherboard.
I run all versions (XP to 8.1) here, so I do have some experience.

I've installed 8.1 several times now and I always install Classic Shell and set it to Windows 7 mode.
I just did another install today, to an OLD IDE 20GB drive. It's running great, on an IDE to SATA adapter.

Good Luck,
TM :cool:

I have classic shell installed, it just doesn't feel the same. I'd rather have win7 instead of a substitute. It's frustrating because the problem I am having seems to be relatively unknown based on internet searches. Thanks

don't get rid of the win 8.1 yet. Just do a dual boot and make 7 as a default OS. Create a new partition for windows 7 and pop the installer in. And then just follow the prompts.

I would still need to enable CSM in the BIOS wouldn't I?

Just do it. I never had to worry about CSM booting. I've been installing and uninstalling Win 7 and Win 8 without bothering with it. Whatever it is the you want to do, the installation process might just do it for you. Some EUFI firmware immediately switch to the BIOS-based CSM booting depending on the type of boot disk's partition table. So just pop the Win 7 installer in and cross your fingers.

Doesn't work when I try to boot from the USB it gives me Windows BSD error

What is the error code (ex. 0xC0000221)?

Well I must have copied it to the USB wrong because it doesn't give the error anymore, but when I set it to boot from CD or USB it just boots up normally like it doesn't recognize it. The CD drive is working because I just used it to factory restore my laptop, so we can rule that out. It's gotta be that damn CSM. I'm planning on calling Toshiba support tomorrow to see if I can get this worked out. I'll post results.

Have you come across this Toshiba site: Windows 8 does not have a USB boot option - TOSHIBA FORUMS (http://forums.toshiba.com/t5/Computer-Troubleshooting/Windows-8-does-not-have-a-USB-boot-option/ta-p/408527)

This is what I'm having trouble with. My BIOS doesn't give the option to do this. I know if has it though, because in the instructions to install my BIOS version by CD, it instructs me to turn on CSM boot.

Well I guess I'm going to have to just stick with windows 8 because customer service told me they were going charge me to walk me through the process of fixing it. That's ridiculous they are going to charge me to show me where the CSM option is in my BIOS

The BIOS screen in the photo that you attached here looks different from the BIOS screen from this Toshiba page:

I know that is the whole dilemma. My Bios is relatively new. Released in December of 2013, so the only thing I can think of is these tutorials are using old BIOS

Just wondering, is that "BIOS utility" you have part of the program called "Desktop Assist"?

No but I do have a program called Toshiba System Settings which bares a striking resemblance to my BIOS

From what I've read, that program can be uninstalled and re-installed. Maybe if you uninstall it, you may be able to boot up to the BIOS screen as we know it (the normal one). From there, you may be able to switch to CSM boot. These are just my thoughts. Up to you if you want to try to do it. Just trying to help.

I hear your worry about how to bot with UEFI.
As BadRobert said, just do it.
However, if you gave 8.1 a few months you would be sold and not miss the slow speed of 7, less security and you would be bored.
Win 8.1 has it all except refresh, without a disc, and reset - same.
Use Chrome instead of MSIE 11.
