I'm trying to make a new .iso with MKUBCD.BAT but every time I run it I get this error

mkisofs: Uh oh, I cant find the boot image 'boot/loader.bin' !

What does it mean and how do I fix it?

Browse to the UBCD root directory (where mkubcd.bat is located) and make sure the file "loader.bin" exists in the "boot" subdirectory. If not, you didn't copy the contents of the UBCD to your harddisk correctly.

Having the same problem, and the loader.bin file is definitely in the boot subdir.
Have reset the NTFS perms for all files in UBCD tree to be RW for everyone - same result.
Error occurs after :-
"Using SCREE001.GIF for ./UBCD/tutorials/nero5/screenshot02.gif (screenshot01.gif)
mkisofs: Uh oh, I cant find the boot image 'boot/loader.bin' !"

Running batch file results in following messages at start:-
C:\UBCD>mkisofs -N -J -joliet-long -D -V "UBCD" -o /ubcd34.iso -b boot/loader.bi
n -no-emul-boot -boot-load-size 4 .
Warning: creating filesystem that does not conform to ISO-9660.
Warning: creating filesystem with (nonstandard) Joliet extensions
but without (standard) Rock Ridge extensions.
It is highly recommended to add Rock Ridge

Have tried mkubcd.sh patch - no change.

Changed slashes for Windows slashes (ie backslashes) - no change.

Tried again with '.' changed to '\ubcd' as :-
C:\UBCD>mkisofs -N -J -joliet-long -D -V "UBCD" -o \ubcd34.iso -b boot\loader.bin -no-emul-boot -boot-load-size 4 \ubcd

Errored at same point with :- (just last 2 lines again)
Using SCREE001.GIF for \ubcd/UBCD/tutorials/nero5/screenshot02.gif (screenshot01.gif)
mkisofs: Error: (NULL POINTER) and \ubcd/boot.catalog have the same Joliet name
mkisofs: Joliet tree sort failed.

loader.bin is in the boot dir. Anyone got any ideas?

You can ignore the warnings, they are alright.

Try doing this from a command prompt:

Code: Select all

cd \ubcd (or whatever dir you placed the UBCD files)
dir mkubcd.*
dir boot\loader.*

and cut-paste the output here. Thanks!

Thanks for reply - output below, although I have now used ImgBurn to create the iso instead, but others may want soln.

I think I know what the problem is, the filename is in the wrong case.

mkisofs is case-sensitive, so it doesn't like to see LOADER.BIN in uppercase.

I suspect some of your other files may have the wrong case as well. Please double-check with contents of CD.

Hmm should it really make a difference under an operating system which is not case sensitive ? ...

wraitda · #9 Post by **wraitda** » Tue Oct 31, 2006 11:39 am

Thanks for that - it worked - didn't realise mkisofs was case sensitive, as I'm running XP!
Had extracted files from the iso using isobuster, and extracting from the ISO tree gave all upper case.
After your suggestion, extracted from Joliet tree & gave all lower case filenames, but still upper case directories! Just changed BOOT to boot & mkisofs ran without failing.

Well that did it! Just uppercased the boot/loader.bin bit and it worked perfectly!

Thanks for your help.
