Technically UBCD 4 Win is Warez, because it's basically a stripped version of Windows XP... since altering windows in anyway isn't exactly legal without MS's written consent. besides if any corp truley cared about Hiren they would have shut him down years ago.
Any how i found a way to combine all three CDs.
just make a custom version of UBCD. before making the iso file i just created a new folder in the UBCD root folder and named it "custom" then i opend magicISO and inserted Hirens boot CD and UBCD4Win and made ISO files from the cds. put the iso files into the custom folder then extracted mkisofs.exe to the UBCD main folder made my ISO file for UBCD by double-clicking mkubcd.bat. then burned the ISO file to CD with MagicISO's builtin burning software.
all you have to do to boot the two iso files is select "drop to console" navigate to the custom folder and type "diskemu" then the filename( example: "diskemu UBCD4WIN.iso")
i couldn't get it to work from the custom menu.
i saw the "how to" section of the forum, and basically followed that.
UPDATE: Looks like your stuck with carrying a seperate hiren CD for now. After some Testing i found that this method doesn't seem to work with hirens and UBCD4Win. probably issue created by emulation...anyhow i'll keep messing with MagicISO to see if i can get it working
i'm currently working on a project to get everything working. perhapes the virus scan on Hirens just doesn't work with v7.8. i'll look in to it some more.
