You are right, it doesn't happen with any other O/S except iOS where you have to pay people/Apple to fix it (or reset the OS) or Windows where the stock response is "reinstall the O/S"

How valuable is the data on your laptop? Did you have it backed up? If so, stop worrying and just take the Windows approach. If not... Find someone local to you who is able to fix it (good luck with that...)

As for the rest - you come over as someone who expects someone else to fix your shit for free with no information other than "waaaa it's stopped working"

This may help How to as Smart Questions

Fwiw, based on your brief description of symptoms, I would say your boot device file system is broken somehow. To fix you need to mount it on another booted OS and fsck it (however if it mounts, copy valuable data off onto other media, then fsck it) . How to do that is left to your powers of Google. Not warranting my response in any way.

Best of luck.

First up - I know nothing about your specific problem. Let me add some pointers as to why you may be having difficulty...

You need to provide way more detail than a screenshot (which shows nothing really) and "why is it broken?"

What is the hardware, what is the boot device, what is the boot loader (and version), what does the boot loader config look like... There could be any number of things that stop the boot, including a corrupt boot file.

No one is able to diagnose your problem from the information you have provided.

If you are unwilling to grab a USB stick from a retailer, boot a different OS image and try some diags on your original file system you may well find people reluctant to help (for free...)

After it is dumped and converted into a binary file, binwalk should (hopefully) recognize it as a filesystem such as squashfs/ubifs/jffs2

That there, from your link, tells you what you need to know... Or at least points you in the right direction.

Your dump will not have stuff like variable names in it - compilers don't tend to keep those unless it's a debug image; variable names are for meatsacks.

Once you have converted the dump to a binary file (dunno how you would do that these days; there ought to be a tool but you could always write one... If that thought fills you with dread then you are probably in the wrong game) binwalk might tell you what file system the data is and you could mount that and have a peer at what's there.

Sadly there is no recipe book on how to go about it - you just have to make educated guesses (make use of Google/other research tools/usenet/hardware hacker fora) and keep trying stuff and making notes till it works...

Good luck!

Or at least the promise of money which may, or more likely may not, materialise.

I use it on every phone handset at work... I guess it's the switch PoE not the pc mobo but the effect is the same. If you are talking pc mobo PoE I guess it could be handy if you had a PoE camera...

Why doesn't my copy have that cover? Sigh. Those were the days.

How did the flap and, indeed, starship have enough control authority after the burn up during re-entry, to complete the soft landing?

The booster done good as well of course...

Flipping awesome outcome... Beers all around.

One thing other answers have missed is that some ssds encrypt data before writing and obviously after reading (this prevents a swap the storage controller type attack) A secure erase on such a device consists of changing the read/write key. Takes milliseconds. Irrevocable (unless you find a way to read previous contents of the key storage)

drawings do not exploit anyone.

Hmmm. I think you will find in many jurisdictions that they are treated as if they do.

Which is of course how BSE got going - only they were feeding sheep brains to cows... Seems the feed manufacturers never learn.

Is this Westminster just being Tory or is it Wales bashing?

I suspect that if you look at all (! There aren't many, if any, left) UK steel works they all have less spent on them by the Govt. than similar plant in other countries...

Temperature is not scalar

Messers Rankine, Kelvin and even Fahrenheit would beg to differ... Temperature is scalar, however it's effects on living things is generally not mostly owing to chemistry.

The claim that a 40° C jump in Sub-Zero temperatures is tolerable, but wouldn't be in the UK or whatever they're saying in this article... That's nonsense

Au contraire my dear fellow. For a human, the article is entirely correct. A rise of 40° C in a particularly cold place is indeed tolerable for a human. A similar rise in, say, the UK today would put the temperature at 52° C - hotter than Death Valley on a well above average day and considerably less tolerable.

Of course a single recorded rise in temperature isn't a good indication of climate...
