SOLVED!! - See cdbob post in thread for explanation and workarounds. Issue was with design assumption in chain.c32

Original Post

Check you command line for mkisofs against this one (which is known to be generally working):

Well, all used files system or exension ignores case.
-iso-level 4 : allows lower and upper case, Boot is a valid name
-R : allows lower and upper case, Boot is a valid name
-J -joliet-long : allows lower and upper case, Boot is a valid name

Uppercase required folders and files at hard disk first. Run given command next.
Or use -force-uppercase at some versions.

I have been trying to get this to work for a while now and so far nothing I seem to be doing can get it to work properly. On USB it works great but as soon as I get it into ISO format the BOOTMGR cannot find the BCD file it seems.

Can anyone give me a hand? Alternatively is there another place I could ask?

Which files exist at hard disk?
Can you run: dir BOOT /s /b

Does exist files:
BOOT\BCD
BOOT\BOOT.SDI
BOOT\BOOTFIX.BIN
Case is importand.

Which bootmgr do you use?
Do you use Vista, SP1, SP2, WAIK, Windows 7

Which BCD do you use?
Do you use a default file? Do you use a edited file?

Which bootmgr entry do you use at isolinux.cfg?
Post your bootmgr isolinux.cfg entry.

Which ISO file size do you get? Do you get a file greater 4GB ?

Which mkisofs -version do you use?

Cross checked myself:Bootmgr does find BCD, PE does boot.

or

I downloaded UBCD 5.0b12 and updated the syslinux/isolinux files from syslinux 3.82.

I am using Sun Virtual Box to test these ISOs.



C:\ubcd-stripped\BOOT\BCD
C:\ubcd-stripped\BOOT\BOOT.SDI
C:\ubcd-stripped\BOOT\BOOTFIX.BIN
C:\ubcd-stripped\BOOT\etfsboot.com
C:\ubcd-stripped\BOOT\isolinux
C:\ubcd-stripped\BOOT\syslinux
C:\ubcd-stripped\BOOT\isolinux\isolinux.bin
C:\ubcd-stripped\BOOT\isolinux\isolinux.cfg
C:\ubcd-stripped\BOOT\syslinux\chain.c32
C:\ubcd-stripped\BOOT\syslinux\ldlinux.sys
C:\ubcd-stripped\BOOT\syslinux\memdisk
C:\ubcd-stripped\BOOT\syslinux\menu.c32
C:\ubcd-stripped\BOOT\syslinux\reboot.c32
C:\ubcd-stripped\BOOT\syslinux\syslinux.cfg
C:\ubcd-stripped\BOOT\syslinux\vesamenu.c32
Yes see above.

I downloaded the Vista Recovery Environment ISO from here: http://neosmart.net/blog/2008/windows-vist...-disc-download/
I downloaded the 32bit edition, extracted with 7zip and properly renamed the files and folders to all caps (see above).

I confirmed that the plain ISO boots to Vista Recovery environment.

BCD file is default one from this ISO and not modified.

etfsboot.com was not included on this iso so I downloaded it from here: http://www.mydigitallife.info/wp-content/u...01/etfsboot.com
isolinux.cfg entry

and then ubcd/menus/syslinux/main.cfg looks like this:
ISO size is 385mb with ubcd and the Vista Recovery environment. With the ubcd files and BOOT.WIM stripped out its 5MB.

I am using the one included with UBCD 5.0b12 = mkisofs 2.01-bootcd.ru (i386-pc-mingw32)
I tried both the those mkisfofs lines and the result is still the same (File: \Boot\BCD Status: 0xc000000e Info: An error occurred while attempting to read the boot configuration data.)

The way I create the iso is run administrator command prompt, CD c:\ubcd-stripped\ubcd\tools\win32\ubcd2iso\, and then run either ubcd2iso or ubcd2iso1 or ubcd2iso2.

the script variables are: (script) (ubcdfileslocation eg. c:\ubcd-stripped) (location/name of what i want the ISO to be eg. c:\ubcd-stripped.iso)

ubcd2iso = original build script from ubcd 5.0b12

ubcd2iso1 = modified mkisofs line to look like first one in quote:

ubcd2iso2 = modified mkisofs line to look like your second one in quote:


Please feel free to download the files I provided in the beginning of the thread. They are the same files I am using.

What do I seem to be missing?

thanks,

Chain.32 does cause current behaviour.

Try the classic approach: boot sector file.
Isolinux support extension .bin. Hence the mkisofs -graft-points

Back to chain.32:
http://www.boot-land.net/forums/index.php?...ost&p=72127
Bootmgr dosn't detect a CD anymore. Bootmgr search BCD at a hard disk layout and dosn't find one.

There is a fixed chain.32 abailable at above link. Bootmgr does find BCD at CD.

It works!!! Thank you!

I am going to use the patched chain.c32 for now and maybe in the future I will switch to the classic approach you mentioned (but I dont want an extra menu item just for when booting ISO). For my USB installs they are using latest chain.c32 from syslinux and the iso uses all the same files except the script replaces the chain.c32 with the patched one for the iso.

Thank you very much,
