tusk Posted October 9, 2011 Share Posted October 9, 2011 been playing with Grub4DOS (bloody great little thing!)here's where i think i'm being difficult or maybe just not understanding whats already explained (too much caffeine, not enough sleep!)I have built up a multiboot USB (16gb), that has XP Home/Pro/MCE, all vista & 7 (32 & 64bit), Bit defender, UBCD, MEMtest, Ophcrack & some other bootable recovery tools. This all works 100%, but I want to build it up on a dual layer DVD, mostly as we get some awkward systems that don't boot from USB or LAN, but have DVD-DL drives (or the ability to add one). Also it means i can carry 1 dvd, instead of about 15 cd's/dvd's!With the optimize option in oscdimg.exe, i get from an 8.4GB drive to a 7.4GB ISO (perfect for DL), but it wont boot. Everything I tried it on gives the following error:Try (hdd0,0): NTFS5: No grldrTry (hdd0,1): NTFS5: No grldrTry (hdd0,2): NTFS5: No grldrTry (hdd0,3): NTFS5: Invalid or nullBIOS: Drive=0x0, H=1, S=1Try (fd0): invalid or nullCannot find grldrPress space bar to hold the screen, any other key to boot previous mbr....The oscdimg command i used isoscdimg.exe -d -u1 -o -bd:\super_aio\boot\syslinux\grldr.mbrWhat am I doing wrong? Am i asking the impossible or just being plain stupid - be honest, only way i learn!If its not possible, anyone got a suggestion of getting non-usb or PXE booting computers to work via a cd option? not something i've looked at, so any suggestions welcome!Thanks in advance!

tusk Posted October 10, 2011 Author Share Posted October 10, 2011 OK, after some much needed sleep & a good walk to work in the lovely English weather (its raining, cold & windy) I have decided I have been somewhat retarded.The grldr.mbr is looking for grldr on a hdd or fdd, not a optical drive! Think i need to modify that file! lolI'll post any findings or more questions on here as i get there! Link to comment Share on other sites More sharing options...

(depending on the version you might need to check CaSe of the grldr - or GRLDR file)WHY are you using grldr.mbr? (the file to be used as no-emulation bootsector is grldr and NOT grld.mbr).jaclaz Link to comment Share on other sites More sharing options...

cdob Posted October 10, 2011 Share Posted October 10, 2011 The grldr.mbr is looking for grldr on a hdd or fdd, not a optical drive! Yes, use grldr as boot file: -bd:\super_aio\boot\syslinux\grldrTest this at available BIOS. You may use a CD-RW for basic testing.It's Grub4DOS 0.4.4.Use a current version instead http://code.google.com/p/grub4dos-chenall/downloads/listGrub4dos is case sensitive at case sensitive file system.Use something like chainloader /bootmgr || chainloader /BOOTMGR I've checked the case & used the -d switch to force lower caseSelect file systems and extensions for your collection. That's difficult decission.I'm out of DVD-DL at the momentThere are virtual machines for testing. Link to comment Share on other sites More sharing options...
jaclaz Posted October 10, 2011 Share Posted October 10, 2011 Just for the record "0.4.4" makes NO sense. The 0.4.4 (as well as current 0.4.5 "series") is identified by an ADDITIONAL date.Latest of the 0.4.4 series (recommended) is this one:Better if you use a later version (of the 0.4.5 series, from the site cdob gave you)jaclaz Link to comment Share on other sites More sharing options...
tusk Posted October 11, 2011 Author Share Posted October 11, 2011 Cheers guys! Didn't get a chance last night to try it, ended up chilling with the misses!! There are virtual machines for testing.Don't use a virtual machine on my laptop, its WAY too slow, installed a mini-xp tester & it took 20mins to get to a boot screen Really need a new laptop! I have some time today at work, along with a few discs, so will hopefully give it a shot! Link to comment Share on other sites More sharing options...
tusk Posted October 18, 2011 Author Share Posted October 18, 2011 Ok decided to give up!Just going to a bootable USB with a kickdisk. After optimization, i can get it to a 10GB iso (ish), so not going on a DVD.On the plus side have learnt some more stuff about Grub (so not a huge loss!)

tusk Posted October 20, 2011 Author Share Posted October 20, 2011 (edited) Giving up is NEVER an option! well, trying to squeeze it down further is the killing point of the project!But, USB + kickdisk = kick a** on old BIOS's I managed to get it down from 14GB to 10GB, but no way a DVD-DL will handle it. Not to mention that the Vista & 7 bootmgr's being difficult.I have decided though to follow both of these ideas to create a nice multiboot USB with not only Windows XP/Vista & 7 installers, but also some linux based utils too! Got a few days off next week to play with both these ideas, so will see what happens! The links i've been thinking of are the following - 02 - How to create a USB drive that will install one of many choices of Windows OS's (Vista/Win7/Server 2008/XP)&Create a Multiboot Multipartition USB with Syslinux and Grub4DosSuppose best do some "work" now as I'm actually at work & being paid - although nothing to do & no boss present!
