Booting from a USB flash drive

The way to boot a device on a temporary basis is using the F12 key during boot and use the Boot Device Menu.  Make sure and select the UEFI version if you are running a UEFI configuration.  You don't need to change anything and the next time you boot, the normal boot priority will be used.

Macrium Reflect recovery media will boot a UEFI system just fine - it's best to make the media on the system you want to use the recovery for, and do so AFTER the system is fully configured teh way you want to run it.

Thanks for the replies.

Unfortunetely they do not answer my question. Within the set up F12 or F2 you have multiple uptions you have to deal with in order to boot from a USB drive in the Dell Inspireon 1556.

You have to tweak secure boot, legacy , UEFI etc in a sequence I don't know. Last time tried I could not boot into the laptop.

Please someone a step by step procedure on how to do this in able to use my recovery USB drive from Macrium.

If the drive was made with PE 4.0 (see below), all you need to do is press F12 and boot from it.

Thanks but entering F12 does not give you a straight forward option to choose USB for booting. It's not like it was in the past. My reply points to my frustration.

Please advise

How was the flash drive prepared?  What version of Reflect?  And did you choose to make it with PE 4.0 ?

Thanks everybody. Looks like I got it right this time. F12 and the option to boot from my Sansdisk  USB showed up. Went ahead and it booted into Macrium.

Thanks
