mobiusonline Posted April 23, 2009 Share Posted April 23, 2009 (edited) I have a multibood cd that runs with CDShell. I am adding a few applications that I can not get to work with CDShell, but have been able to get to work with Grub4Dos. I do not have time to convert the whole layout at the moment. However, is it possible to have the CDShell load a Grub4Dos menu setup, and if so, how can I go about adding it to my CDShell script?Thanks in advance,M Edited April 23, 2009 by mobiusonline Link to comment Share on other sites More sharing options...

mobiusonline Posted April 23, 2009 Author Share Posted April 23, 2009 Thanks for the help, and once you gave me that, it made perfect sense...However, when I try to run the command to load grldr from my CDShell, I get this error:Error: File cannot be larger than 64kb.The file grldr has an out of the box size of 210kb.The command I am using is:chain \grub\grldrThe Grub4Dos files are on the same CD as the CDShell.What am I missing?

jaclaz Posted April 24, 2009 Share Posted April 24, 2009 Do you normally chainload the loader or a 2048 bytes CD bootsector invoking the loader?I mean, what happens if you follow loosely the flyakite's guide:http://flyakite.msfn.org/xpprosp1.htmand change:SETUPLDR.BIN ->GRUB4DOS.BIN (or any 8+3 name)I386->GRUB (or any 4 letter name)And you place a copy of grldr renamed to GRUB4DOS.BIN in directory \GRUB\ ?Do read also the issues that may happen when renaming grldr:http://diddy.boot-land.net/grub4dos/files/grldrmbr.htmOr try chainloading grldr.mbr instead of grldr directly from CDSHELL. BTW, just for the record, grub4dos is CaSe SeNsItIvE on CDFS.jaclaz Link to comment Share on other sites More sharing options...

jaclaz Posted April 24, 2009 Share Posted April 24, 2009 Worked like a charm. Thanks for the assistance.Which one?The hacked bootsector or the chainloading of grldr.mbr ?However, happy it worked. jaclaz Link to comment Share on other sites More sharing options...
mobiusonline Posted April 25, 2009 Author Share Posted April 25, 2009 Sorry, should have been more clear. The hacked boot sector. The .mbr did not work for me, and I tried that one first since it seemed easiest. Once I did it, I realized the other one was the easier.Thanks again,M Link to comment Share on other sites More sharing options...
