how to create multi-boot USB?

Do you have any spaces in the ISO filename?
I got the configuration file error if I have any spaces in the filename or I use "Try unlisted ISO (via SYSLINUX)".

What works for me is an ISO with no spaces in the filename using "Try unlisted ISO (GRUB)".

If you do get the error, close YUMI and restart it, then try it this way.

i would like to add some rescue stuff on too like hirens.. XBOOT seems to work but i left it running and came back from work with error and i think its when its went to add win7 AIO which is larger than 4Gb - it was supposed to use 19Gb but only 8Gb had been used:

just seen this, I replaced the spaces with underscores so that should work?

Yes, that may be what caused your problem.
Also use "Try unlisted ISO (GRUB)"

just got this with unlisted ISO with SYSLINUX



i will try grub

Did you try using "Try unlisted ISO (GRUB)" ?

If you did try that option, did it work for you ?

yes its worked brill thanks..now i have a super USB stick with XP,Vista,7,8,8.1 AIO OEM's on, Hirens.. Kaspersky, Bit-Def and Avira and that windows password cracker....along with Hirens and D7 and many portable apps for IN windows

also

WSUS OFFLINE fully updated for all versions of windows and office

so can do just about anything with this stick from a technicians view.... can install windows AND update it (just top up WSUS regularly)

BRILL
THANKS :)

You're welcome and glad to hear it worked.
Sounds like a nice tool-set you have

Multi-boot flash drives are great. I call them Magic Sticks. It sure beats going through a slippery stack of DVD's/Cd's to find what you want, especially if you are stressed out with computer problems lol.
