    This is a continuation of...

    mantra,

    After you install Win7 and confirm it's working you can reconnect the data cable to your Win11 SSD and boot each OS from the BIOS as you have been doing.

    But using BIBM (BootIt Bare Metal) gives you a far better way to multi-boot. Leaving technical details for later...

    BIBM supports up to 32 drives.
    BIBM supports over 200 primary partitions per drive. Each primary partition can be an OS partition or a data partition.
    Your many OS can be on HD0 or on several other drives.
    BIBM is installed in a small FAT partition on HD0.
    OS can be hidden from each other so there is no opportunity for cross talk.

    mantra,

    Yes, BIBM can be uninstalled in one second.

    If you have ten OS, on any drives, in any combination, say 4 drives....

    1 2 3
    4 5 6 7
    8 9
    10

    You decide to boot OS 6. The other 9 OS will be hidden when OS 6 boots.

    You decide to boot OS 3. The other 9 OS will be hidden when OS 3 boots.

    BIBM has a one month free trial.

    BIU (BootIt UEFI) has a one month free trial.

    If you buy the BootIt Collection you get both apps. Each is licensed for 5 home computers.

    hi
    just a question , to resize partitions created in BIBM , can I use image for linux partition work ?
    just because it's very fast image for linux to create / restore and work with partitions ,while image for dos is more slow
    and in the BIBM boot mangager , is there an option to let hide the os even they are installed on different hd ?
    I'm planing to try tonight , sadly the guide is all in english :(
    thanks

    Sure, you can use IFL Partition Work,

    You can hide OS on any HD. But even better, if you make the disk EMBR then don't add that partition to MBR Details. Then Windows won't think a partition is present and Disk Manager will show Unallocated Free Space.

    MBR Details is the Partition Table on that drive. With an EMBR Disk you might have 10 partitions on the drive but the only partitions Windows will see are those partitions in MBR Details. MBR Details has a maximum of 4 primary partitions.

    I forgot, use the Unlimited Primaries setting.

    A MBR disk has the partition table in LBA 0. LBA 0 is the MBR. It's limited to 4 primary partitions.

    An EMBR disk also has an EMBR in LBA 1 to LBA 62. Each sector can hold 4 partition entries. BIBM can move entries from the EMBR to the MBR. This is controlled by you, the user. Windows only sees partitions that you move into the MBR.

    Let's say the EMBR drive has 20 primary partitions. You can select any 4 partitions that you want Windows to see. These 4 partitions will be in a Boot Item. You can have multiple Boot Items so all partitions can be accessible. You can select up to 4 primary partitions on each of your drives to be in a Boot Item.

    For example, let's say you had 5 OS and a common data partition on a drive. You want to create a Boot Item for OS 4. You only need the OS 4 partition and the common data partition in the MBR Details. The other partitions are not relevant for that OS. Windows won't see them.

    With MBR you dont need to install windows fixed on any drive. user only need to create a partition with boot record which is 1MB (1024KB). in that case it is possible to create other partitions, primary or extended, where user can install so many windows he like to.
    this were practice here on another machine where i had XP, win7, win8.1, win10 - before win7 and 10 moved to another machine. and thus i can delete any other windows from a running windows and install a new windows on that empty place now - without to care about my boot partition. when xp got futile i deleted files from that partition were not needed and kept the boot information, then i reduced the partition and got free space for another partition for any reason. i was able to spread my windows OS overall my two hdd and still did not care about the boot record. and thats same with UEFI, one EFI systempartition for all, 1 recovery and the rest for free. GPT can contain 128 partitions, i have doubt that a single computer will ever reach this with regular usage.

    hi
    can i ask you converting EMBR or GTP to MBR does it need windows 7/8/10/11 installation dvd/usb ?
    i'm reading the terabyte tutorial https://www.terabyteunlimited.com/kb/kb-articles/converting-a-gpt-data-or-windows-disk-to-mbr-embr/
    and seems that it does need windows installation dvd/usb
    are there other tool that can do it without windows installation dvd/usb like diskgenius or macrium ?
    thanks

    Correct. You only need BIBM. The web page doesn't apply to what you will be doing.

    The BIBM install creates an EMBR on HD0 by default.


    (EMBR is Extended Master Boot Record)

    Some BIBM examples.

    Partitions on HD0 (6 primaries and Free Space)...

    PXL_20230602_204657661.jpg


    Boot Menu...

    PXL_20230602_204750299.jpg

    Win11 Boot Item. Note, only two partitions are in the partition table on HD0. Only one partition is in the partition table on HD1 and HD2. By choice. The other OS are hidden by not being in the partition table...

    Partitions are added to the partition table by selecting "Fill"

    Partitions are removed from the partition table by selecting "Clear"

    hi Brian
    I have tried , but it did not install the bootmanager
    I have tried to resize the w11 partitions about 8mb but nothing
    I have tried to resize system reserverd nothing , i have tried to resize the last w11 partion nothing
    BIBM doesn't even detect the hd0 , i have plugged the w11 as hd0 , but seems it does check the bios drives list and order :doubt:
    but w11 is really not worth to use , the application bar is huge and in the last version could not been resized , and there is nothing about w11 that I like , just used for a morning
    I will try again, but i spent almost one morning without luck
    and now i haven't an empty drive because i thought to install bibm on an empty drive and after restore the image on it
    thanks Brian

    @Brian K
    Have you ever tried booting a Ventoy usb flash from a multiboot BIBM menu? If not, would you be willing to do a simple test with it to verify my issue with BIBM described here.? It should only take 3-5 min of your time. Unpack, install on spare flash with Ventoy2Disk.exe and copy BIBM iso to the flash and then reboot. Ventoy Windows version should now be listed in the boot menu.

    Hi
    does Ventoy work with mbr very well and what can make it better than yumi or Universal USB Installer ?

    about partition program like paragon ,partition work and so on , I have never understood the meaning of hide a parition or a drive , hide from who ?
    hiding (i guess partition work - image for linux has not this option) a drive or partions could be "seen" by other operation sytem during the boot?
    thanks

    Adric,

    Can you wait until next week? I'm on a fishing trip and don't have a computer.
