8:01 the vista installation detected ntldr (the boot loader 2000 and xp use), but starting with vista windows uses bootmgr and i think it just places bootmgr (the newer windows boot loader) on the partition with the existing installations, and bootmgr allows you to go to ntldr under "earlier version of windows"

19:29 the MBR partition scheme only supports 4 primary partitions, and you've used all of them up by this point, though you could've made the 4th one an extended partition with multiple logical drives and potentially install other versions of windows but i'm not sure how well that would work, if at all

You're the pro-version of me. I installed all Windows versions as a VM and you installed them on a physical PC.
Anyway gave you a sub.

you could likely install everything from 3.1 to 10 on a single computer using just three partitions
- one fat16 partition for dos, 3.1 and 95
- one fat32 partition for 98 and me
- one ntfs partition for 2000-10

19:20 it's because you have the max number of PRIMARY partitions. however, if you create a LOGICAL partition from diskmgmt, you can have as many as your hard drive can handle. try it next

19:16 A MBR disk can contain a maximum of 4 primary partitions.

guess who made it into the youtube algorithim

I felt just as much disappointment as you when Windows 2000 blue screened after installing all those other OSes, great video!

Maybe at some day you have to revisit the 5 counts
- Vista and above boot fine from extended partitions
- Windows 8 and above can boot from a VHD file stored on a NTFS partition, as long as the free space on the NTFS partition is more than the maximum allowed grow size of the VHD. It can even install directly to a VHD file if during setup you open cmd window and mount one with DISKPART. (I used this sometimes to install another Windows version on a machine without repartitioning to test driver support).
- I believe Windows 2000 can also dual-boot with DOS; and from DOS you can start Windows 1.0 to Windows ME all installed on a single FAT partition.
- If you start with Windows 8 (or 7 unofficially) you can install in UEFI mode on GPT Partition which has no limit of primary or extended partitions (other than free disk space)

Man that’s a lot of operating systems for a single hard drive

19:15 The reason why the Windows 10 installer said "You have the maximum number of partitions is because for GPT Disks you can have up to 128 partitions and for MBR Disks you can have only 4 partitions.

To convert from MBR to GPT you can use third party apps like MiniTool Partition Wizard which has support from Windows XP to Windows 11 whether its 32 or 64 bit. Or, you could use AOMEI Partition Assistant which has support for Windows 7 to Windows 11. And also when installing MiniTool, DO NOT CHOOSE THE PRO TRIAL because when you try to do something it will not let you do it until you buy the pro version. If you choose the pro trial dont worry, this can be fixed by reinstalling MiniTool

This was really nice! I kinda want to do a triple boot of Windows XP, 7 and 10 on a X58 motherboard and i7-920 that I managed to pick up recently.
Out of interest, what specs are the machine used for this test? I reckon Windows 7 was probably the best OS for your machine, with Windows XP not being too bad either if you installed all of the drivers.

I feel like I can practically smell the Druaga1 influence on this and I am so excited and here for it.
I miss that man lmao

7:53 to 8:02 how did he go from sounding like a trusted adult to sounding like a crazy teenager

Best part of the video is the ice pic

[FireMemes_Productions]

Wha- WAIT... Is that the NINTENDO 3DS SETTINGS Bring back a lotta nostaliga

[Jack-lyvt]

how do you not have more subscribers? this is W content

[heheboifollow]

(2:16) "i took a picture of ice while i was gone" *got me*

[retrogamer]

If you use extended partitions you can get more versions installed. I currently have xp-10 dual booted on my laptop

You can install up to 128 operating systems on a UEFI system with a GPT disk, as GPT supports up to 128 partitions by default. However, managing that many OS installations can be complex due to boot management and system resource demands. Most users find it practical to dual boot two or three OSes.
