I had a Similar problem with My Toshiba Satellite L50-B where every time I tried booting from USB it wouldn't I searched numerous website all saying the same thing in the end I gave up and started testing BIOS settings Myself and found that if I changed the USB 3.0 setting to disable so it boots the laptop into thinking its using USB ports in 2.0 mode I instantly Am able to boot Windows setup or anything similar with no problems at all hope this may help some of You. :)

From my own tests with toshiba click mini, you'll be able to boot vfat usb key with a well formated efi boot directory and file (/efi in your USB key). Bios even in 5.10 release does not support legacy boot.

Windows 8.1 32 bits usb key build from Windows 8.1 is able to boot on click mini (ntfs filesystem) while 64 bits release of Windows 8.1 usb key build from Windows 8.1 64 bits does not boot on click mini. I suspect, as discuss on toshiba eu forum, toshiba click mini bios to boot using 32 bits efi boot sheme on efi/boot/bootia32.efi.

Try boot with a gparted usb key : get the files from efi/boot (include a grub.cfg file) and use this on new USB key you create, you'll be successfull to boot linux modifying grub.cfg. Try the Manjaro (ArchLinux) distribution, this distribution as the best hardware support at that time.

Fedlet works out of the box (although super unstable because the window manager is to heavy). What I did was install xubuntu while stealing someone else's efi encryption stuff. Then I just did some grub hacking and it worked (I think I ended up comparing what fedlet was doing vs the default xubuntu disk). Once I booted I installed xubuntu and then I had to do the same procedure for the installed OS.

I tried everything add infinitum and eventualy took the back off machine unplugged cmos battery plugged back in, put computer back together and hey presto no problem.there are loads of instructibles on youtube for the process ,not particularly easy.

I have a toshiba c655d-s5518, on that computer there is a jumper labeled xxx just above the DDR3 memory modules (towards battery), if you short the jumper while powering on it clears the BIOS password. on Some other C655D the jumper is labeled B500.

there are 2 pins next to either the ram or the cmos battery. mine was next to the ram. youll see them next to the ram all alone. turn the computer off. take a flathead scredriver and touch the two pins. hold it there while you power on the computer. the computer should turn on and then shut down. now power it on normally and the password should be gone. ive done this in a dozen c655 and c855s

pull out the bios ic name with winbond with 8 pins put it in the programmer download the bios file from toshiba webste extract the file there will be file with extension rom or bin try to make me picture i will guide you then programme the ic it will be claire i am very familiar with this

1. Starting with the computer fully off, turn it on by pressing and releasing the power button. Immediately and repeatedly tap the Esc key, until the message "Check system. Then press (F1) key" appears on the screen.

For some reasons it could happen that no PC Serial No. and Challenge Code will displayed instead of "Not Certified" appears. In this case remove the AC-adapter and the battery for a short time and try it again.

hey, little update on the computer. Sorry I didn't specify, but yes, I did try the escape key method, with no success. It would always beep every time any key was pressed after around 4-5 seconds of holding or pressing any key. The only keys that don't beep are 4 keys in the top right.

Additional update: I think the ram is missing. There's a connector on the top of the motherboard that is accessible by simply taking off the keyboard. I have been confused as to what it might be for until now. I'll do more research, but i think it might not be working because of a lack of ram.

The computer is completely working again. After I quickly assumed it was a lack of ram that prevented the computer from working, I later realized the computer had internal ram, and the connector under the keyboard is merely a expansion slot for ram. I figured this out by trying a random idea I thought up of: Take out the cmos batteries. (which were corroded slightly on the connectors.) so i took out the batteries for a few hours, and upon re-plugging them in and turning the computer back on, It finally allowed me to access the bios normally. (It was then when I found out I didn't need to buy ram.) I later made a totally legal copy of windows 98 and installed it using the SD to IDE i've mentioned before. It works fine and I've been able to play doom on it.

Hey, sorry I didn't specify. Yes, I tried that method, with no luck. all it does is start beeping after holding the button for 4-5 seconds. It also starts beeping if any key is pressed a number of times. What I mean is that each time a key is pressed a short beep can be heard.

I tried it and as soon as the screen comes on, It says: "Ready for BIOS update. place the BIOS update Diskette in the drive, and press any key when ready to proceed," it was also doing long beep sounds for a minute or so and then stopped. I saw that there were bios updates on Toshiba's website. I have some floppy disks laying around and a USB external floppy drive, do you think I should try to update the bios?

I think yes. If you hear the sound after holding ESC or F1, then the keys itself are working, so if you are not able to enter bios with a valid key combination, the only thing I suspect is invalid (partialy broken or sth.) bios program. Luckyly the key-combination to update bios is working, so try to upload a new one. Good luck.
