I used WinSetup to put multiple Rescue CD grub4dos compatible iso linux files for loading antivirus programs from usb pen drive.
All of them give errors with not being able to find/install the linux filesystem. For example in Kaspersky Rescue CD I get :
dracut Warning: Can't mount root file system

Dropping to debug shell.

Dracut:/#

In AVG/Avira/DrWeb I get errors as well but DrWeb doesn't get errors but just seem to load for ever it's linux based system files.
Why is there a difference? Some suggest I need to use newer grub4dos version. If I use WAREZ and fedora/kubuntu there are no problems at all.
I don't want to use like 4-5 cd when one usb pen drive can do the same thing. It is not ahci/driver related problem.
Maybe I need to extract those antivir iso's and use another method for importing? I used WinSetupFromUSB_1-0-beta8.exe

Just a thought - I used NTFS and maybe those linux based rescue cd's want SysLinux based option from WinSetup?

Changing grub4dos to Syslinux (or viceversa) doesn't change the filesystem.
A number of minimal Linux Distro's (like the ones that come with Antivirus) do not have support for NTFS (in the sense that they cannot reside on NTFS formatted filesystems).
You may need a FAT32 formattted stick.

You should NOT use WAREZ, or however don't talk about them here.

I have another spared 4 GB pen drive so I will try on it. It won't need NTFS for such small space lol. Thanks for the help!

That means those ISOs are not grub4dos compatible, in terms of ability to boot from an emulated CD (by grub4dos) and finish booting without need of extra steps.

To rephrase- one cannot boot ANY ISO this way.

You may want to try Sardu, which supports many types of AV rescue disks, or create manually menu.lst entries for each ISO you want to boot, many examples could be found here:
