A boot loader is a program that is found by the system BIOS (or UEFI) in the boot sector of your storage device (floppy or hard drive’s Master_boot_record), and which locates and starts your operating_system ( Linux ) for you.
Is rEFInd better than GRUB?
rEFInd has more eye candy, as you point out. rEFInd is more reliable at booting Windows with Secure Boot active. (See this bug report for information on a moderately common problem with GRUB that doesn’t affect rEFInd.) rEFInd can launch BIOS-mode boot loaders; GRUB can’t.
Why do we use Linux?
The Linux system is very stable and is not prone to crashes. The Linux OS runs exactly as fast as it did when first installed, even after several years. … Unlike Windows, you need not reboot a Linux server after every update or patch.

- Local CD/DVD—Enables boot from local CD/DVD drive.
- Local Floppy—Enables boot from local floppy drive.
- SD Card—Enables boot from SD Card.
Does RAM contain boot software?
So, we can clearly say, that the bootloader is neither stored in ROM, nor in RAM, It is actually stored on Hard disk (or other Boot device, such as bootable CDROM, USB drives etc) , precisely speaking the first sector of the hard disk, which is of size 512 bytes and often referred to as the boot-sector.
