Hi,

I installed a Windows 98 virtual machine on virtualbox 1.6 it works fine.

I have to move this vdi to another computer.
I used vboxmanager clonevdi to copy the VDI file.

After that i try with an other virtualbox with the same settings

And i have the message :

FATAL : INT18 : boot failure

Any ideas ?

I also receive the FATAL : INT18 : boot failure message.

I used gparted to copy a windows vmdk to vdi.
After that I booted the VM from an XP cd and ran FIXBOOT and FIXMBR.
Now I can't get past the "FATAL : INT18 : boot failure" message.

Any luck on your Win98 situation?

I also have the same problem after cloning INT18 boot failure and have tried Fixdisk/Fixmbr. I couldn't find any help in the FAQ cited.

Does anyone have any suggestions? ...thx

btw... I'm not cloning from a previous version (VB 1.5 etc.) but from a VMDK

I've had a look at the source code. VBox uses the MandrakeSoft BIOS written for use with QEMU. The Int18 entry point just calls a routine called int18_panic_msg which puts out the message that you saw INT18: BOOT FAILURE. This shows the vintage of your bootstrap. What the old FAT16 bootstraps used to do was first to try to boot from drive A then from the HDD partition 0, then if this failed they would call INT 18 to load the ROM BASIC system. Needless to say VBox doesn't support ROM Basic

So what is really happening is that your Win95 bootstrap isn't finding your boot partition. Just a dumb Q. You did remember to activate partition zero didn't you as well as getting its partition type correct?

TerryE - you got it - I missed the all important step of making the partition bootable. doh!
Thank you for such a quick (and correct!) response!

I could be smug at this point, but the truth is that I did a clone a couple of week's ago and it just wouldn't boot, so I was doing hexdumps of the MBR, etc. and going though it with a fine tooth comb, pulling my hair out (how's that for a good mixed mataphore), when the penny dropped and I realised that I had forgot to activate the boot partition!!!! Durrrr!
