my M$ goes up in smoke

Ephemeral · Posted: Mon Jun 23, 2025 11:20 pm Post subject: my M$ goes up in smoke

Dunno whether im angry or what... still deciding Laughing

Earlier in the day id put an Atheros wireless PCI card in...

So there i was in matlab trying to do work and M$ decided to BSOD... Mad

Presumably some sort of IRQ problem as it occured when i started playing music as well

So the m$ install is most probably monged for want of a better word... im posting from Ubuntu on same machine...

So what are my options to get M$ up and running again?.. cos itll wipe grub ... but i dont want to reinstall Ubuntu

and has anyone tried Matlab in virtualisation? I know a Unix/Linux version exists but legality would be an issue

actually, your license file is what is key Wink

if its on the same machine your perfectly legit according to the matlab folks Wink

I had this discussion with them. Just copy your key over to your linux installation. The *nix installer is on the cd Wink

matlab in virtual just sounds like a bad idea, especially if your doing complex math... which is what it was intended for Razz

as for the windows installation, yeah it will bork up your grub, but it shouldnt bork with your *nix install. Just install winders to the same partition. Once you've done that, pop in your *nix cd and reinstall grub, and re-add the windows boot option. Wink

not hard at all. let us know if you need help Very Happy

Of course, if you don't need windows for anything other than matlab, and there are no legal issues, and you have no problem getting the linux version to work, I'd just blow away the windows partition and use it for something more useful.

erk the story gets worse...

tried to recover some files.. copy from win to external HD (USB)

went off for lunch.. this is 90GB or so ..

and the damn thing crashed...

now the machine wont even boot

---Verifying DMI Pool Data...

---DISK BOOT FAILURE

just wondering if the disk itself has now had it... time to unearth ultimate boot CD Sad

Well the hard disk survived Cool

used the samsung util on UBCD

Programmings not going so well though... im wondering about using an OO language instead...

Having difficult with data structure in matlab

Im trying to use L-systems (a re-writing language) to produce a tree with the following qualities

3D
Random branching
Realistic look (width / diameter reduction)
And an applied external force bending the branches (wind), governing growth direction
Animation

I can get a basic random 3D L-system going in matlab.. but trying to incorporate these other things is proving troublesome

For the sake of re-addressing the original question. You could reinstall windows (yes this overwrites the MBR). But then all you have to do is boot to a linux live CD/DVD and reinstall grub into the MBR. As long as you don't wipe out your linux partitions when you reinstall windows you'll be fine.

I could re-iterate how reintall GRUB, but this link takes care of it nicely (and covers some circumstances I wouldn't have thought of)

It's possible your drive has failed (did it make any clicking noises or smoke?). It's also possible a cable has come loose in your case - you might want to double-check your drive cabling. Getting stuck at Verifying DMI Pool Data usually indicates a hardware problem, but I've not found any single reason why it ever gets stuck there (or gives the Disk Boot Failure).

Another option would be to pop in the Windows install disk (if we're talking XP here) and try to boot into the recovery console, type 'fixmbr' and see if that lets you boot back into Windows. Obviously this move will destroy your grub install on the mbr, but that's easily fixed as platinummonkey states above.

thanks for the responses

yeah disk is fine, was able to verify using samsung util on ultimate boot cd

reinstalled windows

going to fix ubuntu when its convienent

or i might just re-install it...

i have partitions mounted permently as directories

such as /mediapt which refers to a partition

never got my head round setting that up properly manually but most distros installers allow u to specify that... whilst windows was dying it seemed to be having trouble accessing those partitions .. despite the fact they were non OS partitions.. just had files in
