I have swithed on fast boot in the intel ivy bridge ultrabook and now I am unable o enter bios setup.
When you switch on Fast boot from BIOS settings, it sets "Setup prompt timeout" to 0 seconds. Still you can enter in BIOS setup by continuosly pressing DEL or F2 keys at the start. If this is not helping, try resetting you BIOS by removing power of BIOS, wait for 10 mins. and plug power to BIOS then try powering your Ultabook.
Next time you switch on fast boot, on confirmation screen - select NO, this will keep Setup prompt timeout to whatever value is set (default is 1 sec) then save settings and exit. This will keep setup prompt for 1 second and will give a chance to enter BIOS.
Hi, windows os has been Bios lock for not format the same.
