Hi, I've been an old-school techie since 1986 and all this new-fangled technology REALLY confuses me..... I want to convert a new 4TB HDD from MBR to GPT so I can use the full 4TB capacity of my new HDD. I also want to re-install Windows 7 OS (64-bit) on this HDD. My current Intel-DH67BL motherboard supports UEFI but it is currently set to legacy BIOS mode because till date I was using 4x 2TB HDDs in my PC case. Now my existing of storage is filled, and I presently need 4x 4TB HDDs (yes, 16TB) for storing my 4K photographs. Can you please MAKE A VIDEO that explains this process of conversion for newbies like me? Perhaps someone can please point me to some videos that explain this BIOS-->UEFI and MBR-->GPT process? I am sure it will help me and thousands of other users who have older Core i5 systems BUT they need 4TB or higher capacity drives to store large volumes of data like me...... NOTE: I can easily buy a Samsung 860 EVO 500GB SSD to use just as a system disk (OS only) with the OS, Primary, system, boot, page-file & dump on that disk itself.... while I can use separate 4TB SATA mechanical HDDs for all my installed Programs, Documents, Media, Data etc (I have 4 bays for 3.5 inch HDDs).

When I tried to do boot camp windows for my Mac Pro 5,1, I had a lot of issues. But mostly they are related to this UEFI/GPT vs Legacy/MBR. At first I didn't have blank DVDs, and I tried to make boot camp using usb. However, since the Usb drive was formatted as FAT32, then first issue I had is that the FAT32 format does not allow any single file bigger than 4gb, but the there is a file called install.wim in the windows 10 ISO file does exceed that size. Then I tried to split that file into two smaller ones, then I was told that the system cannot be installed on disk of MBR. After fixing that, then I was told that the system cannot be installed on partition of FAT32. Unfortunately I did not go through this path, and finally I bought some blank DVDs from Amazon to use DVD+R to install windows 10. Unfortunately, by using DVD, it uses Legacy/MBR, so you have to format a whole disk of MBR schema. Since MacOS does not use that schema, so you cannot access that MBR disk. So my question is how to install windows 10 on a boot camp partition which is actually on GPT disk schema? My target is to install both MacOS and Windows 10 on same NVME m.2 SSD to achieve best performance for both OS. Thanks

I just bought a mini pc with an internal msata 128GB drive. I also put a 240GB SSD drive in the PC. I don't play games. I formatted both drives to get rid of windows 10 pro.
I was thinking of using two partitions on the msata drive for bionicpup and fossapup. I would like four partitions on the SSD drive so I can install four different Linux distros to try out. I really want to keep this simple so in bionicpup I want to use grub4dos for my boot menu.
Can I just use legacy instead of UEFI? I use audacity and cd burning software for my CD collection. I'm replacing HP Compaq 8000f Elite Ultra-slim Desktop PC from around 2008.
Pretty basic stuff when it comes to computing on my part.
Thanks for the advice!!!!!-

Hi...! PLEASE HELP ME IF YOU CAN. I bought my computer in 2012 and I have a one terabyte HDD (4 drives), I checked my partition style, it was of an MBR partition style. The BIOS settings looks new and I see a lot of graphic informations and on the top is written -UEFI BIOS UTILITY-. I entered the boot menu and both UEFI and Legacy boot option is enabled... I have formatted a flash drive using mbr system by Rufus software. I'm using windows 7 at the moment and I'm going to move to Windows 10. Can I proceed with installing windows 10? Would there be a risk of erasing my disk drives? I'm afraid of loosing my data and its not possible for me to get a backup of the data because more space is not available.

I am reinstalled windows 10 in my laptop with UEFI boot system = GPT Style = Fat 32. After installing the windows I will complete all the driver installation but I am facing some problems like - some third party software wasn't work properly sometimes,
And my desktop was little bit blinking at the time of refresh, and when I play YouTube videos the video will shown sometime yellow hazy style little bit. And I will checked from device manager, and all the drivers was installed properly.
What's the problem is that?

Some older legacy bios on that last boards before UEFI did take over had patches to support detection and GPT on the drives larger than 2TG. This kind of throws off people that were not building at the time or installing large drives. GPT is supported and I have had Windows 10 running on one of these boards. What kind of sucks with some back up utilities on servers and virtualization was the weird server time that EFI was a thing. Really sucks when you are trying to do an emergency automatic spin up a virtual server.

Hi Chris. I'm 8minutes, 03 seconds into the video and have a question for you. I recently tried dual booting the latest version of ubuntu with windows 7 home premium and noticed that the ubuntu boot loader took over the loading of either windows or linux. It looked like the font size it used for the loader was extremely small and hard to read. Is there any way to inscrease the font size of this boot loader (assuming it was grub?). Thank-you!

On so old computer is not possible to install Windows 11 as Legacy Boot but when I change it to UEFI boot, then it is possible to install Windows 11 without any problem.
My question is, to Keep the boot as UEFI and use the computer as it is would it harm the computer and other programs work properly?
