Totally enormous hard drive sizes supported (like, REALLY big).Just as UEFI is replacing the BIOS, GPT is replacing MBR. It has several limitations, namely only 4 primary partitions are allowed, and the maximum size for an MBR hard drive is 2TB.
CONVERT MBR TO GPT ISO WINDOWS
In other words, the Boot Sector has a Boot Loader that tells Windows to fire up.
CONVERT MBR TO GPT ISO CODE
The boot loader is a small chunk of code that usually loads a larger boot loader from another partition on the drive. Master Boot Record, or MBR, is basically the boot sector on a hard drive that contains a boot loader for the installed operating system and information about the drive’s logical partitions. So what’s the difference between MBR and GPT? Note the last item above: UEFI supports huge hard drives as long as the drive is using GPT. Chances are, if your puter is only a few years old, it probably already has UEFI instead of the traditional and outdated BIOS. In short, UEFI is the future of computers – at least when they boot up. Support for ginormous hard drives with GPT.Modular and flexible design for future-proofness.A fancy graphical configuration interface.UEFI, or Unified Extensible Firmware Interface, is like a new version of the BIOS that does more stuff – and better. Once done, it then looks for an operating system to boot, starts it, and then takes a back seat. The BIOS looks at all the hardware in your puter, allocates memory to different devices, and more or less sets up all the hardware to work nicely together. When you power your puter on, it does all kinds of exciting things. The Basic Input Output System, or BIOS, is firmware that sits in a chip on your motherboard. I hadn’t heard anything about it, which is pretty weird considering how awesome it is. It turns out Microsoft has made the process really easy!įirst of all, thanks go to Wingwong for shooting me an e-mail and letting me know about mbr2gpt. Well, okay… First of all, what does all that mean?Īnd second, how on earth do you convert your MBR drive to the new GPT format without having to reinstall Windows? Nowadays, the BIOS is rapidly giving way to UEFI, which provides all kinds of benefits.Īt the same time, hard drives have sort of evolved, so now we’re supposed to use GPT instead of MBR. In the olden days, your puter had a BIOS.
