Dual Boot starting with ubuntu

**garvinrick4** · June 1st, 2011

you have 45gig of data on your primary partition (sda1), whats with that?

Hi jerrys,
Looks like OP has about 41 gig of /home going on, does not have a seperate /home.
Maybe OP has it all backed up and wants to make a new partition for XP who really knows
only got about 8 gig left on drive. EDIT: just saw OP's last post he has 20 gig to play with.

RFRFG: make sure you got your stuff backed up before you start playing with partition table
or you are likely to lose it.

Code:

sudo parted -l

(lower case L)
This will give partitions in gigs.
##Have a nice day.

back to your question in post#4. if you don't have ubuntu installed, then you have no use for swap or the extended partition. so yes, wipe it if you want.

ubuntu is my current os.

i've learned that my bios is capable of booting from a usb drive, and i have a compatible usb drive to boot from, but when i tried setting it up (it was suggested to remove hard drives first and install to usb drive) on my PC, it wouldn't boot my altered CD (i must have done something wrong) and now my PC booting is out of order. so now i have another problem... i was using these directions: http://tdoui.webs.com/Install%20And%...From%20USB.pdf

Run this script in a live cd or usb:
download script to DESKTOP and then run this line of code in a terminal will put a file
on desktop called RESULTS copy and paste here. After copied here highlight whole thing
and hit the # in upper right or Message box will be easier to read bootscript.

We are going to purge and then reinstall grub to mbr:
Put in Live Cd or Usb and use Try Ubuntu and with internet working. (firefox works to get online)
Now copy and paste these one at a time.

Code:


	Code:
	sudo mount /dev/sda1 /mnt

	Code:
	for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done

	Code:
	sudo cp /etc/resolv.conf  /mnt/etc/resolv.conf

	Code:
	sudo chroot /mnt

	Code:
	apt-get update
Should get update with no errors, if errors your internet was not working in live cd or usb

	Code:
	apt-get purge grub grub-common grub-pc

	Code:
	apt-get install grub-common grub-pc
Use tab to toggle and say OK to put in sda

	Code:
	grub-install /dev/sda
 above redundant but just in case

	Code:
	update-grub

	Code:
	exit

	Code:
	for i in /dev/pts /dev /proc /sys; do sudo umount /mnt$i ; done

	Code:
	sudo umount /mnt

	Code:
	sudo reboot

A few redundant commands but just want to make sure it is in sda and updated.

**RFRFG** · June 2nd, 2011

i'm sorry, what do you mean by live cd or usb?

**garvinrick4** · June 2nd, 2011

A install CD of Ubuntu and use Try Ubuntu instead of install Ubuntu when it asks.
Will then go to a Ubuntu desktop and in upper right hand corner is network applet
get your internet going and then you can open a terminal to copy and paste each line
of code by: ctrl/alt/t :at same time and terminal will pop up.

## Put CD in tray and reboot so it boots off of Cd and then choose Try Ubuntu:
Better to ask question than do it wrong, Ok. Or the USB flash drive.

**garvinrick4** · June 2nd, 2011

how did you get the bootscript? What did you use? If you are booting and using the 60 gig
drive, let me know. That is all I see in bootscript, I think you are capable of booting into your
Hard drive. If you are let me know.
