Toshiba cl45. Can't change boot UEFI boot Mode. Impossible after disabling Secure Boot.

Disclaimer: BORING VIDEO FOR INFORMATIONAL PURPOSES
For those who have a toshiba laptop model cl45, it is impossible to change to boot from UEFI mode to non UEFI CSM.
Bios is Ver. 5.1

1) I booted into bios
2) Then I went to Security on Left and set Secure Boot o Disabled
3) Finally I went to advanced, but the option for "Boot Mode" - UEFI Boot is completely disabled.

I've heard that I need to turn off my machine between step 2 and 3 (which I've tried.) I did a hard shut down too removing the battery. No success at all.

I think this cheap laptop which only has 32gb of internal storage just doesn't have the ability to disable UEFI in bios.

WHY does anyone want UEFI disabled? To re-install windows easily. Basically, you can't easily create a UEFI boot device using windows own usb creation devices. Yes, that's right.. even windows creation tool doesn't do this by default. *sigh

Long story short.. what should have taken me 15 min to reinstall the os took me a few hours because I had to figure out how to create a UEFI usb windows installation

Thanks! Toshiba Satellite C55-B5201 and turning off UEFI it worked by simply disabling Secure Boot.

Yep, I have a dozen of these and Boot Mode is always grayed out. FYI these 32GB machines work great if you know how to use them and manage your expectations. Not a good choice for an only computer since you should wipe & reinstall windows every major update. But a fine coffee shop/travel laptop for email, Youtube, Netflix and light general use. Chrome takes one whole GB on a system where Windows 10 usually leaves 10GB or less free, so forget Office or any other big apps. Windows updates often require you to add external memory (SD card or USB drive) just to have room to install, so here's how I install updates and wipe the whole 32GB memory for a clean install. Use another computer to "create media" on a USB drive, typically ~3GB. Set your Toshiba boot order to USB first then power up to install Windows. Select CUSTOM INSTALLATION, then delete all partitions and install. Give it an hour to grind away, then your computer is as good as new. Click Windows update a few times to get the latest drivers and you're done. Plan to do that twice a year, so store/backup ALL of your files on a nano USB drive or SD card. Hint: get a tiny white "Macbook micro SD card adapter" off Ebay for a dollar and add a 32GB micro SD card. Doubles your memory and fits flush in the laptop.

Thanks man for the Toshiba Satellite C50-A -0FN, disabling secure boot allowed me to change UEFI :D

If you still can't access these settings, you can install an operating system using a GPT partition. If you are using a program such a Rufus, you can choose "GPT partition scheme for UEFI" in the second drop-down menu, labeled "partition scheme and target system type".

Hope this helps!

Hey thanks a lot sir it work on my Toshiba the minute I disabled the security

[monstak]

you have to create and register user and master bios pwds and this allows the mode to become change able!

If you have this problem, enter bios via F2 not F12, you're welcome

[jdeshetlerII]

You were sooo close! You have to disable secure boot to change to CSM this is a MUST to run Ubuntu. I do appreciate you going down the right path in the security settings it did ultimately help

[absurdnoodles]

I turned off the security boot but the boot mode is still greyed out anyone got a solution for this

[Enya]

thank u man!!!! i cant change uefi boot but i watchd ur video and now i can change and i can install w7 ♡♡♡

[kerryalai]

My UEFI setting is displayed, I pressed it after disabling the security which worked for my Toshiba satellite C55-B5302. After doing so, and restarting back to the BIOS menu, the HDD recovery option pops up, but will not let me press yes. It only lets me press no. When I press yes, it freezes. Please help if you can

[AlexandruDanIon]

as i can see there you have not registered a user or supervisor, Once you will do that you will have levels of interaction with BIOS full-restricted-read only!!! Choose full and the greyed UEFI will become blue :) also keep the secure boot off!

[treystar]

my uefi setting is showing
I had to disable secure boot then select CSM I was able to install windows7 onto it

[pizzel]

the only way i was able to resolve this is by removing the battery, there are two screws holding the battery, take those out, let the laptop stay off for about 1hr if you can open inside the laptop and remove the cmos battery too, once thats done the laptop will reset to factory defaults, go to bios->advanced->, system configurations you will be able to change the boot from uefi to cms boot.

Hi i have the same problem .. did you find the solution or someone else please !!

[Josh.Davidson]

Same problem on CL15t. Wanted to put Windows 7, but CL15t doesn't even HAVE the CFM option. Booting from UEFI makes Windows 7 freeze at the Starting Windows screen on this machine.

[smoothdigital]

After you disable the security save and exit. After enter to the bios again and you will have the option to change uefi mode.

[LycanSound]

You need Rufus 2, 4 select boot image ( win 10) format key fat 32 using GPT partition scheme for UEFI because CSM in bios boot option is greyed out, hope this helps

[magsofalltrades]

i am able to fix that problem by simply registering a supervisor account and enabling full access then disabling secure boot. that's all...

i just got one of these laptops, It has windows 10 on it, problem is there is no audio driver for win10, so i wanted to install win7 on it, it wouldn't allow me to do anything, so i searched, i saw someone else switch from EUFI to CCR or what ever it is, he said that will allow me to install, i went in to the bios and it wasn't highlighted for me to be able to change from EUFI, so i went and switched to unsecure mode, went back and it was highlighted and i was allowed to change it from EUFI, Now i'm just in the process of installing win7 as i type. seems a cool laptop other than the silly win10
