Windows 7: BSOD W7 Unmountable Boot Volume (tried everything I can think of)

CMOS battery is the soldered in type - how wonderful! This is the most annoying "won't boot" job I've had in a while!

I don't have another battery to replace it with at the moment (I know I could hack it with a regular 2032 but I don't know how advisable that is, I'm capable but never actually tried it)

I've slapped another HDD in it which I know is faulty - just for giggles to see what it would do. It tries to load the recovery module but stops, however I think this may be down to the fact that the drive came out of my own laptop a while ago, and although it has W7 on it, it's 64bit OS and this repair one is 32 so I'm not surprised it won't work. Just running out of options before ordering parts.

I'm at the point where I doubt it's the RAM because I'm skeptical that both sticks have developed errors simultaneously. Has anyone had that happen?

I also doubt it's the CMOS battery, it's holding date and time. I forgot to check the voltage before I reassembled it but I can always do that later I guess. Time to order a new HDD me thinks.

That is just so strange....a soldered in CMOS battery. I've not seen that in Many Years! And Never in any of the Toshiba laptops that I've had to work on, including my own.

The worse case I've had to deal with was one little lappy that had two little 1.5v cells strapped together, in series, and then soldered onto a short cable that plugged into a connector on the motherboard.
I just cut the two little cells off of their straps and soldered those onto a CR-2032, wrapped that in black tape and plugged it back into the motherboard and the laptop came up and worked perfectly.

Just one memory cell in just one stick of ram that's gone bad, can take down the whole system, depending on just where that one cell is located.

I wish I had that laptop here, because I'd love to troubleshoot that problem. I have plenty of hard drives, ram sticks and CMOS batteries and I'm fairly certain that I could affect a repair. If you were closer, I'd say just bring that little PC on down here and I'll fix it for you.

I said that one day, in an email, to a guy out in Arkansas, sort of joking, and a few days later a UPS truck pulled up in my driveway and delivered to me the guys PC in a big brown box. (along with a check for the repair, upgrade and return shipping) But I see you're not in the USA, so I think I'm safe.

I do wish you all the best,

I've seen many kinds of things, a BIOS bug causing system freezes (on my own pc), a loose wire in the PSU, a bad pin in the socket and all RAM sticks faulty as well.

I said that once as well, where it turned out to be a loose wire in the PSU. Unfortunately he either couldn't affort it or we were too far from each other (or both).

Ha! No you're safe! I've never encountered a soldered one either, but I have heard of them. I also run a Tosh (my own specs) but haven't had it apart yet other than to swap out the SSD which is hardly dismantling territory.

I've had to change the odd CMOS batt over the years but only ever in desktops because they won't hold RTC and produce that BIOS error, always fixed with a replacement batt.

I don't know how old this laptop I'm working on is, but it's not ancient. It's a 17" and has Wi-Fi etc so not a complete dinosaur. At least not my by definition!

It's a real puzzler at the moment, and whilst I don't claim to be a professional anything, I'm pretty competent and not easily stumped. I think I might just put the screws into a pot and take a break from it for tonight, resume in the morning. Although what's left to try without a fresh HDD I'm not sure. Oh I will check the voltage on that CMOS batt anyway but I'd be surprised if this turns out to be the issue. Still, everyone always has something new to learn!

Thanks for the input everyone, I'l keep you posted!

SD60659. To change the Time Zone, Left Click on the clock at the bottom RH corner of the screen & select Change Date & Time Settings, when that opens, select Change Time Zone, then click on the little arrow & scroll through the list to find your Time Zone, select that & be sure to click the OK button before exiting.

Having the right Time, Date & Time Zone are important.

OK so here's where we're at. I've tested the battery and I'm getting 3.78V.

So I stole the HDD out of my mothers laptop when she wasn't looking, whacked it in and up it came! No errors, just started right up! So I can only assume thoroughly roasted hard drive. I'm still at a loss as to why it won't boot from other media with the faulty HDD installed.

Hi SD60659,

I am glad that you are getting to the bottom of your issue.
I would have tried swapping out the HDD initially as a matter of course so as to disregard that as a potential problem.
One good point here is that if you were to ever have the same sort of problem in the future you now have the troubleshooting knowledge at your disposal!
