Dual Booting Debian and Windows XP


I've been running Debian Linux on my personal computers for years. Recently my son found a Dell Optiplex 745 (one of the small format machines that I prefer) at a very reasonable price – with a valid license for Windows XP. It was time to upgrade both software and hardware.

As my old Dell GX270 (with Debian Lenny) was working just fine, I decided to try for a dual-boot install on the new box.  I found this tutorial online.

I downloaded gparted, as suggested, and burned the iso to a CD. I then cleaned up the Windows XP installation and did a defrag. I ended up with the large majority of the 80Gb disc free.

I then booted gparted and followed the tutorial to shrink the Windows partition to ~ 20Gb. A re-boot proved Windows XP was still happy.
 
I downloaded the latest Debian Testing – Wheezy – as a netinst (network install) iso and again burned a CD. After connecting the new machine to the network, I booted the netinst CD and did a routine install for a desktop. Things went well until the install asked me if I wanted to install the grub bootloader on the MBR. At this point grub was supposed to detect the Windows XP partition and edit the grub menu accordingly. But it did not. I had no choice but to continue with the Wheezy installation.

Wheezy booted fine, but I had no easy way to boot to Windows. Some quick research revealed a problem with grub detecting the Windows partition during the Wheezy install. The note said that running (as root):

grub-update

would repair the problem. It did. Grub detected Windows XP and added it to the bootloader menu.

I then had a dual-boot machine with Debian Wheezy (testing) and Windows XP. Both run fine.

I would not normally bother with Windows, but there are still several Amateur Radio Windows applications which do not have a functional equivalent in Linux – notably antenna modeling software.

Plus, it was interesting to try my first dual-boot..

2012 Flight of the Bumblebees



This year, I returned to the same site as in in 2011 – just a couple of miles to the west of Longhorn Cavern State Park here in Texas.

The location offers good views to the north and west and there are nicely placed live oaks and cedars to support wire antennas. I used a fishing pole and 5 pound-test line to toss a small sinker over the trees. I can't imagine why anyone would want to use anything else – but then I have been fishing for a long time. This year I did it in four casts. But, it usually it takes more...

This view is to the north.

 I hung a 20m dipole E-W and then a 40M half-wave in roughly the same direction. I used a KI6J half-wave tuner to match the 40M antenna.

I did get hot while hanging the wires. It was over 90 when I arrived at 11 and 104F at 4 PM when I quit – not as bad as last year when it was 107 as the FOTBB finished!

I used the K1 and an AME Single Lever Paddle. I had several liters of water, sunscreen and bug repellent. There was a nice breeze most of the time. I sprayed both myself and the ground near me with the DEET bug stuff. Worked great – though the wood ants on the cedar were curious about the K1.

After working 20M for a while, I tried 40M with no luck. I then hooked up the 40M half-wave as a long wire for 15M and used a 20M half-wave as a single radial to see if the K1 could find a match. It did and I made 7 Qs before returning to 20M.

The closest Bumblebee to me was Scott, W5ESE at Pedernales Falls State Park, about 30 miles SSE. I could just barely detect him, and he could barely hear me – but on different bands, so no QSO for us. My closest state worked was New Mexico and best DX was Maine. I made 54 QSOs and worked 26 SPCs.
Here is a photo of Packsaddle Mountain from my FOTBB location. This is the nearest SOTA site to me (W5T/EF-003) and I would love to activate it but access is a problem. So near, and yet so far.
Douglas Adams inspired my Bumblebee number.  I had a great time once again. Thanks to all those who heard me.  Had fun.
