For changing boot order in any Computer. Simply press 'Del" Key or 'F10' Key. This will take you to the CMOS set up program in the BIOS Setup. Here generally boot order is present in the 'Advance Chip Set Feature) option.You can change the boot order from there by pressing 'Up or 'Down' arrow. Sandeep Chadha Cell:9560311765, Delhi, India.

There is no official order; the boot order can be set or changed on most modern computers.
Boot is the 'verb' . Boot loader is the set of code which is executed while computer boots.

The "bad or missing operating system" error message during boot-up typically occurs due to issues such as a corrupted boot sector, damaged system files, or a misconfigured BIOS/UEFI setting. It can also result from a failing hard drive or incorrect connections, which prevent the system from detecting the operating system. Additionally, if the boot order is not set properly, the computer may try to boot from a non-bootable device.
The most thorough way of testing your RAM would be using a boot-up memory test (unless your computer has a built-in RAM test in its BIOS, which can be accessed by pushing F1 or F2 when the computer first turns on). Here's a link to an iso image you can burn to a CD. After burning it, you would boot the computer from the CD. If it doesn't boot from the CD, you might need to change your boot order from the bios. Set the CD drive as the primary boot location and if it still isn't booting from the CD, you may not have burned it correctly. http://www.memtest86.com/download.HTML
Get a boot disk/usb for either the system you wish to install on it, and there should be an option to do this, alternatively you can use a linux system to do this. In order for any of these to work you must first have the boot order in your BIOS set to prioritise usb and or disk drive, otherwise it wont check there before booting your system.
Most, if not all, Operating Systems modify your systems boot instructions to give the option of what to boot from,also some computers have a command that you can use(such as F11,depends on your computer)to go into your boot options menu. I think using Super GRUB disc you would be able to easily set up your Boot file.
