Hi All - I have just bought a Toshiba Satellite laptop. Before installing everything I wanted to partition the hard drive, for various reasons. To do so, I installed EASUS Pro. (Have used that many, many times on my W7 PC without a problem.) Anyway, it went away to resize the boot partition and now I can't do a !@#%$ing thing. The laptop boots to a 0xc0000225 error screen, and that's it. I entered the UEFI Firmware Settings, and managed to firstly change the fn keys to standard (YAY!) but I CANNOT use the F10 key to save the boot priority to CD/DVD or anything else, so I have nowhere to go from there.
Any useful suggestions would be greatly appreciated. I have literally no idea what to do, am hundreds of miles from any physical support, and so have a totally useless, very expensive laptop on my desk.
OK - I have fixed the boot priority thing, thanks. The BSOD followed an attempt to repartition the HDD as mentioned above. In the end I was able to configure the UEFI boot options by trial and error with the keys in that particular "window" of the settings. I am installing Windows 7, if I can. Not looking brilliant at this stage. Thanks for your reply.
