Are you seeing all hidden + system files in Windows Explorer? I ask because the kernel.dat is a file from Acronis.
In the original Acronis UFD, if all the files are in the root (as oppose to some sub-directory), then you should also see that kernel.dat there, in the same (root) directory as "ramdisk.dat". If the original files are not originally from the root of the original Acronis UFD, then please report where exactly they were.
If indeed all the original files from Acronis were at the root directory, then copy them to the root directory of your customized UBCD UFD and the "acronis.cfg
" should be:
APPEND initrd=/ramdisk.dat vga=0x314 ramdisk_size=40000 quiet
I made some very little changes from your previously posted cfg, but they might make all the difference (specially /
ramdisk.dat, but pay attention to all the changes).
The above cfg file is valid IF
indeed all the original Acronis files should be in the root of the UFD, and don't forget the addition to the custom.cfg I mentioned before, using the correct "acronis.cfg".
I want to be clear: in this case, you shall change the "syslinux.cfg" file from Acronis to "acronis.cfg" to minimize a potential problem with SYSLINUX.
Then when you boot, you select "user-defined" and then wait those 10 seconds for "ati" to start (no pressing <tab>, nor anything else, just wait and see what happens).
If this works, we can improve it a little bit more, but the mentioned ".dat" files should come from Acronis. If it doesn't work at all, please report the exact original path of each file from the original Acronis UFD and the exact content of the original "syslinux.cfg" from Acronis that you know to be working.
