for BT4 changes

you have to create changes directory from windows sesion on fat32 and you have to remove read only setting.

c:\changes



for BT3 changes/

you gave to create ext3 partition (you can use qtparted for creation from any othe linux sesion)

/dev/sdb3

and in this partition create directory changes

in main USB there is
------------------------------


main sdb1 fat32 partition in USB


boot/
bt3/
bt4/
changes/

I can't see that being the problem, i've just had friends reproduce the process just following the instructions in this post. But then taking into account that three of you haven't been successful I'm slightly thrown through a loop...

I'm in the loop with ya. It should be just as easy as you explained it. But for some reason it ignores the BT4 entries.

Well, at least the boot folder work, some success

doing this on my hard disk and using grub works, heres my grub entries.

Hope this helps! It's wonderful having it on the hard disk and on a stick for when you don't have the laptop at a customers

[thunderwing]

doing this on my hard disk and using grub

I've also done this, its great.

[akintoo]

when i tried to dual boot i got the problem of "It just highlights bt3 and start auto boot countdown i try selecting BT4beta again and same thing happens over and over."

so i

extracted iso to desktop renamed boot folder to start then copied start and bt4 folder to usb.

then went to syslinux.cfg in start folder and changed every instance of /boot/vmlinuz and /boot/initrd.gz to /start/vmlinuz and /start/initrd.gz then copied all the entries from that file to the syslinux.cfg file in the boot folder.

now everything is working fine.

no need to run bootinst.bat or bootinst.sh.

Hope this helps someone.

Finding a few ways of doing this along with persistent changes.

For persistent changes i just make a folder called persistent and then make 2 folders inside there called bt3 and bt4 . inside bt3 and bt4 i make a folder called changes and then point my boot option to the respective file. Keeps changes all in one place .

Tried your idea with the boot folders only instead of start i made a bt3 and bt4 folder like my persistent folder and pointed everything to the proper place..works as expected.

Tried this both on hard drive and on a kingston stick.

keeps everything in one place and makes updates or changes easier for me.

[hankarun]

I`m doing this another way. First I install bt4 to usb then add bt3 options to the syslinuz.conf and add directory bt3 to the root of usb key and boot files as vmlinuz-bt3, and initrg-bt3.gz. It works like a charm. For persistent changes create a directory named changes, and modify boot entry by addinf changes=/dev/sdb1 (according to your device).

Note: Sorry for my bad eglish.
