Booting from a USB drive

[Bruno]

They both look okay . . . but I do not see the .rpm you downloaded on C: in Windows . . . . where did you store it ?? Bruno

[bcondemi]

under 'linux download'I can move it to c: Should I do that?B(2)

[Bruno]

NO no no . . . . not needed . . . i just need to know where it exactly is.okay let us see:

# ls -al /mnt/win_c/Linux\ download

Bruno

[bcondemi]

[root@localhost root]# ls -al /mnt/win_c/Linux\ downloadtotal 64dr-x------ 1 root root 0 Apr 8 17:04 ./dr-x------ 1 root root 8192 Apr 9 09:05 ../-r-------- 2 root root 55576 Apr 8 17:04 mkinitrd-4.1.12-9tex.i586.rpm[root@localhost root]# B(2)

[Bruno]

Cool !!!now:

# cp /mnt/win_c/Linux\ download/mkinitrd-4.1.12-9tex.i586.rpm  /mnt/sdb1/root# ls -al /mnt/sdb1/root

No reply on the first command is OK and means it was successfulB) Bruno

Just a question.. the ls command is list and the cp command is copy right?

100% corrrect ;)This is looking good so far . . . now we are getting to the point of no return . . . so fasten your seatbelts

# umount /mnt/win_c# mount -t proc none /mnt/sdb1/proc# mount -t none /dev /mnt/sdb1/dev -o bind# chroot /mnt/sdb1

Show me the prompt you are getting before and after the chroot command . . Bruno

[bcondemi]

Okay . . no problem

The Drive light flashed a bit.I assumed that there were 2 spaces between each set of command (I can't cut and paste). Did I assume right?B(2)

[Bruno]

One or two spaces makes no difference . . I only did put them there so the spaces would be clear to you :)Seems indeed like it worked :)Okay next set of commands:

[Bruno]

Bruno: You are doing great . . . . . I am starting to be proud we wear the same name ! ;)Now comes another difficult part we will change the lilo.conf . . . . .

# kwrite /etc/lilo.conf

This will open a text-editor with the lilo.conf file loaded . . . . . . I changes almost every line of it . . so go through it line by line and spot the differences . . and be careful for typos ;)Here is how it should look:

default="Linux-NEW"boot=/dev/sdbmap=/boot/mapkeytable=/boot/livecd.kltpromptnowarntimeout=100message=/boot/messagemenu-scheme=wb:bw:wb:bwimage=/boot/vmlinuz-2.6.10-oci7         label="Linux-OLD"        root=/dev/sdb1        initrd=/boot/initrd-2.6.10-oci7.img        append="devfs=nomount nomce splash=silent"        vga=788        read-onlyimage=/boot/vmlinuz-2.6.10-oci7         label="Linux-NEW"        root=/dev/sdb1        initrd=/boot/usbinitrd.img        append="devfs=nomount nomce splash=silent"        vga=788        read-only other=/dev/sdc1       label="win_c"

When finished editing . . save the file and close the editor . . you will then get the prompt back in the terminal . . . and then I want to check if you did the edit correctly . . so:

 # cat /etc/lilo.conf

D***! hit a snag...[root@localhost /]# kwrite /etc/lilo.confXlib: connection to "localhost:0.0" refused by serverXlib: Invalid MIT-MAGIC-COOKIE-1 keykwrite: cannot connect to X server :0.0[root@localhost /]# kwrite /etc/lilo.confXlib: connection to "localhost:0.0" refused by serverXlib: Invalid MIT-MAGIC-COOKIE-1 keykwrite: cannot connect to X server :0.0[root@localhost /]# I thought I checked the typing....must be something else.....B(2)

[Bruno]

B2 . . . . watch it because I just made changes in the lilo.conf I posted above . . . . :)Give this command:

# set DISPLAY=localhost:0.0

And try againB) Bruno

Just to confirm, I give the set Display command first then re-do the kwrite command?B(2)

Yep . . . that is correct :DB) Bruno

[Bruno]

No Problem . . we do it another way !Leave this terminal OPEN . . . do not touch it . . . but on another desktop open another Konqueror window and type in the addressbar

file:/

And hit EnterYou will see the directories on the / . . . . . one of them is "/mnt" . . open it. . .and you see "/sdb1" . . open it . . and you see the tree of the HD install . . open "/etc" . . . and in "/etc" you will find the file "lilo.conf" . . . rightclick on it and choose from the context menu "Open With" . . and there you can choose an editor . . pick any you want :DB) BrunoPS: Putting "file:/mnt/sdb1/etc" in the addressbar would maybe work quicker . .

[bcondemi]

that worked much better..I edited the file (actually the cut and paste worked on the second desktop) here we are...[root@localhost /]# cat /etc/lilo.confdefault="Linux-NEW"boot=/dev/sdbmap=/boot/mapkeytable=/boot/livecd.kltpromptnowarntimeout=100message=/boot/messagemenu-scheme=wb:bw:wb:bwimage=/boot/vmlinuz-2.6.10-oci7 label="Linux-OLD" root=/dev/sdb1 initrd=/boot/initrd-2.6.10-oci7.img append="devfs=nomount nomce splash=silent" vga=788 read-onlyimage=/boot/vmlinuz-2.6.10-oci7 label="Linux-NEW" root=/dev/sdb1 initrd=/boot/usbinitrd.img append="devfs=nomount nomce splash=silent" vga=788 read-onlyother=/dev/sdc1 label="win_c"[root@localhost /]# B(2)

WOW !!!! . . .Good one !!!!Now the most crucial command

# /sbin/lilo -b /dev/sdb

Show me what you get . . . ;) Bruno

[bcondemi]

[root@localhost /]# /sbin/lilo -b /dev/sdbIgnoring entry 'boot'Added Linux-OLDAdded Linux-NEW *Added win_c[root@localhost /]# B(2)

[Bruno]

BRILLIANT . . . . We are making a home-run here !!!! :DLast commads:First Ctrl+D . . . that will log you out of the chroot and should give your old prompt back. . . . Then:

# umount /mnt/sdb1/dev# umount /mnt/sdb1/proc# umount /mnt/sdb1

Bruno

[bcondemi]

[root@localhost /]# exit[root@localhost root]# umount /mnt/sdb1/dev[root@localhost root]# umount /mnt/sdb1/proc[root@localhost root]# umount /mnt/sdb1umount: /mnt/sdb1: device is busy(almost a home run). Just 1 strike.I have to unmount the 1'st partition. Is there another way?B(2)

[Bruno]

No problem . . . as long as /proc and /dev are umounted it is okay . . . . Now type "reboot" . . and remove the CD and set the BIOS to boot from the USB-HDD . . you will get Lilo with 3 entries: Linux-NEW Linux-OLD Win_c ( Linux-NEW is the default boot and if you do not touch the arrow keys or hit enter it will automatically boot the default . . . hitting Enter will speed things up ) The second one ( Linux-OLD ) is obsolete . . . I left it there just temporary . . we will remove it as soon as you are booted in PCLos HD install The 3rd entry is to boot Windows Okay go for it and try to boot "Linux-NEW" . . . crossing my fingers . . . putting the champagne on ice . . Bruno

[bcondemi]

GRAND SLAM!!!! AND BRUNO WINS THE WORLD SERIES!!!!!!!!!!!!!Outstanding Job!!!thank-you thank-you thank-you!!!Bruno(2)

[bcondemi]

Just a Question. I read somewhere on your website to never hit the reset button on the case. What happens if the USB drive's button gets pushed to off (not that it will) but I guess it will simulate a power loss. Anything tragic will happen?Second question, I will probably edit the time in the lilo.conf file. I should just use any editior to do the job right?Bruno(2)

[Bruno]

HURRRRRAAAAAY !!!!!Wow . . . man . . . . . excellent job !!!!!!!I would like to tweak the lilo a bit more tomorrow . . . . replace Linux-NEW by "PCLos" . . remove the PCLos-OLD . . . And change the name of Win_c into "Windows" . . . but all that is just cosmetic ;)Champagne . . . time to celebrate !!! . . . . Bruno
