Re: [Qemu-devel] Using Qemu to install Linux in a Windows XP disk image

[Brett Bonfield]

I'm still trying to use QemuInstall on Windows XP Pro to install
SimplyMEPIS Linux. You were right -- the initial dd call I was using
was not correct. I've fixed the call, but still haven't made it work.
Here are my tests so far. I'm sorry this is such a long message, but
I've been doing a lot of testing :^)

>From the Mepis.org forums ( http://www.mepis.org/node/view/4066 ):

<begin msg from Mepis forums>

"I've had no problems running SimplyMEPIS from within Qemu as-is... if
you're looking to install it first run:

dd of=hd.img bs=1024 seek=3000000 count=0 

to create a hard disk image (change seek to whatever size you want the
image to be, in this case around 3GB). Then run:

qemu -hda hd.img -cdrom SimplyMEPIS-2004.04.iso -boot d -user-net

You can then install as normal using the MEPIS Installation Center and
from then on boot with:

qemu -hda hd.img -user-net 

You're on your own in finding a tool in windows that does the
equivelant of dd in Linux though."

<end msg from Mepis forums>

I found the Windows equivalent of dd (
http://uranus.it.swin.edu.au/~jn/linux/rawwrite/dd.htm ) and the
developer, John Newbigin, emailed that I should not use

dd of=hd.img bs=1024 seek=3000000 count=0

but should instead

<begin msg from John Newbigin>

"Pick a file which you can read and is larger than 1024 bytes and try 
this command:

dd if=filethatalreadyexists of=newfile.img bs=1k seek=3071999 count=1

here seek is the offset into the newfile to start the writing.  The 
number I am using = 1024 * 3000 - 1 which will give you 3000Meg again."

<end msg from John Newbigin>

I tried this with SimplyMEPIS-2004.04.iso (the last Mepis release),
John Newbigin's dd for Win32, and QemuInstall-0.6.0 and
QemuInstall-20041111. Here are the errors I got:

QemuInstall-0.6.0 (installed to C:\Program Files\Qemu):

dd if=SimplyMEPIS-2004.04.iso of=MEPIS.img bs=1k seek=3071999 count=1

< this created the image >

qemu -hda hd.img -cdrom SimplyMEPIS-2004.04.iso -boot d -user-net

< this didn't seem to do anything >

qemu -hda hd.img -user-net

< this didn't seem to do anything, either >

So I deleted the .img and uninstalled QemuInstall-0.6.0.

--

QemuInstall-20041111 (installed to C:\Program Files\Qemu):

dd if=SimplyMEPIS-2004.04.iso of=MEPIS.img bs=1k seek=3071999 count=1

< this created the image >

qemu -hda hd.img -cdrom SimplyMEPIS-2004.04.iso -boot d -user-net

< screen flashed and I got the following error:
qemu: could not load PC bios '/c/Program Files/Qemu/bios/bios.bin' >

qemu -hda hd.img -user-net
< again the screen flashed and again I got the following error:
qemu: could not load PC bios '/c/Program Files/Qemu/bios/bios.bin' > 

I decided to try using QemuMenu.bat, which I ran from the command line, It said

<begin QemuMenu.bat error>

Boot QEMU using image:
[1] MEPIS

I selected 1. This generated a QEMU window that contained the
following message (slightly abridged):

Plex86/Bochs VGSBios current-cvs 07 Nov 2004

<end QemuMenu.bat error>

Please let me know what I'm doing wrong. Again, thank you for reading
through such a long message.
