Changing Boot Order


To boot your computer to CRD, you need to make sure the BIOS is set to boot from the correct drive (either CD/DVD or USB depending on where you placed the ISO). In most cases, this will require you to manually prioritize the CD/DVD/USB as the boot drive ahead of your usual C: drive. To make this change, you first have to access your computer’s BIOS configuration utility. While the specifics vary from computer to computer, the following steps should be of use to most users:
  • Place the CD/DVD in your drive or insert the USB key as appropriate
  • Shut down your computer. Note – do a full shut down. A soft restart will not clear memory and the BIOS setup might not appear.
  • Turn your computer back on and be ready to react quickly. During system start up, you will see a message similar to one of the following:
  • Press to enter setup
Or
  • Press to open bios configuration utility
Or
  • Press to change boot order
     
It is usually one of the F1 – F12 keys or the DEL key (F2 and DEL are popular). Quickly press whichever key you are requested to press. If you miss it this time, simply try again by shutting down then starting your computer.
  • Having hit the correct key, the bios configuration utility will start. Look for an entry that states ‘Boot Order’, ‘Change Boot Order’, ‘Change Boot Sequence’ or similar. Select it and press enter.
  • Use the arrow keys to select the CD/DVD drive or USB port that you wish to boot from. If you are shown a sequential boot order, make sure CD/DVD/USB (as applicable) is first on the list.
  • Save and exit. Your machine should automatically reboot to the CRD drive, allowing you to use the program.
  

Note: If these instructions do not help then please consult your system manufacturer’s website (or call their support) for more details on how to change boot order.
