When creating a Rebit Recovery Disk, should I choose UEFI or BIOS?

In the Downloads portion of your Rebit dashboard, you’ll find the option to create a Recovery Disk.

While Rebit offers the ability to restore specific files or a subset of files, there are times you may need to completely recover a system. This may be the case if your computer has stopped working, has been hit by a virus, or is in some other state where it is unresponsive.

In this case, you can boot your computer with a Recovery Disk, restore your entire system, and be back up and running without hassle.

Here is some additional information on full-system recovery:

Choosing UEFI or BIOS ISO for Rebit Recovery Disk

The main step in performing a complete recovery for a computer is to download the Rebit Recovery tool and create a USB disk from which you’ll boot. When you go download the Recovery Disk tool, you will see you are presented with two option: UEFI and BIOS.

These terms simply refer to the system that starts with the hardware on your computer. It is the platform that gets things running before Windows boots. This can be handy, as this software is stored on your motherboard and can allow you to boot your computer even if you have a hard drive crash.

However, there are two types and you need to choose the right one for your Rebit Recovery.

Choosing UEFI

You should choose UEFI if you have a relatively modern computer. UEFI is the successor to legacy BIOS. It is used on nearly all computers running Windows 8 or newer. It is likely on most Windows 7 computers as well. UEFI started hitting the PC scene in 2007.

If you are unsure of which version you have, we recommend starting with UEFI. If you don’t have a UEFI-system, it simply won’t boot (you’ll get an access error) and you’ll know to choose BIOS instead.

Choosing BIOS

If you have an older machine (certainly before 2007), then you should start with a BIOS recovery disk. The only difference here is that if you create a BIOS recovery disk, it will likely still boot in UEFI, but will give you trouble during the recovery process. It’s less obvious there is an incompatibility.

Finding your mode in Windows

Now that you have an idea of the two terms, one of the easiest ways to check on Windows is to click Start > Run. Once that opens, type MSInfo32 and hit Enter to open System Information.

In the list, you should see the BIOS Mode line. It will either say UEFI or Legacy.

Finding your mode without Windows

It is possible you are reading this because your computer has crashed and you cannot figure out your system by using Windows. In this case, you should see some indication of UEFI verbiage during the boot process (before you hit your crashed hard drive). It’s hard, however, to give a specific recommendation because this varies by manufacturer.
