Windows 7: How to create multi-boot flash drive

YUMI initially formats a Flash Drive and gives it the Label "MULTIBOOT".

If I change the Label to "MULTIBOOT-2" :-
Will the ISO APP's work the same; and
Will YUMI be able to continue adding/removing ISO's.

Reason :-
I am making a spare copy of my first MultiBoot flash drive (in case the original gets lost or suffers damage),
and I would like to easily distinguish between them.

It should be OK but the only way to be sure is to try it.

Thanks

Situation Update :-

Tried it - Didn't like it -Won't do it again.
I booted into the Flash drive and Linux failed.
I do not know if it was the YUMI linux launcher that failed to launch,
but I think I was able to select a Linux ISO before disaster struck.

I then rebooted into Windows
Oh the Horror
My Secondary 600 GB WDC HDD with all my Macrium image backup files was changed from GPT style to MBR style,
and instead of NTFS it was mostly RAW or Unallocated depending upon whether I believe Windows Disk Management or MiniTool Partition Wizard Professional v7.7
and the monstrous complex GUI Disk Indentity changed to the simple 8 digit hexadecimal number as used by MBR Disks.

AND IN ADDITION
It changed to the same Disk Identity as my 900 GB Samsung HDD which held partitions D:\ and H:\ which held my Browser Profiles and my Portable Tools.
CONSEQUENTLY
Because Windows saw the Samsung after it saw the WDC it decided to blame Samsung for a Disk Signature conflict
and so the Samsung HDD was knocked Offline and partitions D:\ and H:\ still have their contents but not their drive letters.


Fortunately a NON-Experimental Boot Flash with a Macrium ISO was able to create image backups of those partitions,
and then was able to restore those image backups to a "spare" USB2 connected HDD,
and after a reboot back into Windows the only correct drive letter was C:\
and after setting all the wrong partitions to NONE I was able to allocate H:\ and D:\ to the new restored partitions on my "spare" USB2 HDD.

After two hours of desperation I now am back on the Internet again.

I do not know what exactly caused the problem.
I not only changed the Volume Label of the experimental Flash Drive,
I also ran an MBR backup tool on this experimental Flash Drive before I attempted to boot from it.

In view of dire consequences I have no immediate plans for further boot tool experiments.

PLEASE NOTE :-
I really want to regain all my Macrium Image Backup files, BUT I am not in a desperate hurry.
I expect fully qualified advice from the MiniTool Partition Wizard developers in the next 24 hours.
My son purchased the Professional licence for my birthday last year.
Several years ago they responded within 24 hours even though I was a low priority user of the Free version.
Hence with all due respect I am not looking for advice from this forum.

MiniTool Partition Wizard includes a Recovery Wizard,
and years ago the free version 4.? recovered all partitions in my Laptop.
The Professional version 7.7 has analysed and is ready to restore all the partitions on my 600 GB WDC HDD
and I fully expect it to be successful on this situation.
I am however waiting for advice from the developers of Minitool P.W. upon whether (and how) to convert the HDD back to GPT style either before or after Partition Recovery.

N.B. All but the recent Macrium Images were already safely duplicated from my internal 600 GB WDC HDD to an external eSATA connected 930 GB HDD.

Yikes...
