    Hi all

    I used a program in the past to install windows from a current windows install but I cant remember its name and googling it is driving me insane!

    Could anyone think of the prog I used ?

    It basically allowed you to select a ISO then point it at the partition or drive you wanted to install to and bingo.

    Please thoughts before I lose my mind :D

    Cheers

    Normally one would dism apply the wim to the directory and bcdedit the boot config to add the second install, simply running windows install from boot and using a clean target partition also would do it or start setup.exe from the mounted ISO\sources folder and select the partition to install it on. All should result in a dual boot situation.

    My personal suggestion is don't mess with partitions.

    Just use native vhds

    em I meant I was not messing with partitions it was just the defaults that was confusing me..

    Can you explain some about VHDs ?

    Are they not what are used for virtualbox etc ?

    They were and still are, but since w7/server 2008r2 they are bootable as well.

    • Very flexible and handy

    • boot the same disk natively or inside hyper-v/virtualbox

    • a single file to copy to do a full OS backup.

    • a single file to copy to move installs to another system

    • they can reside in a pendrive, mbr hdd, uefi hdd

    • unlimited number of installations can be stored on a single partition,

    • and so on

    Winntsetup makes monkey proof to use them, but also manually they are pretty easy to manage

    oh right sounds handy and I guess can be compressed to the moon also if needed ?

    To boot natively VHD/VHDx must reside in an uncompressed / not deduplicated FS/Folder

    BUT

    Nothing prevent to compress the FS inside the VHD, which is what I currently do (using both NTFS native compression and W10 style LZX compression)

    Doing so you can have a whole 64 bit system in something like 6GB and a 32bit system in less than 5GB. Obviously if you put your Doc/Img/Download directory outside the OS VHD, which is also handy to have your docs in a single place no matter which OS you boot.
