That is odd. However iirc it is an option in the bios.
Fwiw telling grub to uefi boot will not work if the boot device doesn't have uefi support (and trying to boot in bios mode from a uefi disk fails as well... Been there got the T-shirt)
To get the install media to boot you could try removing the laptop storage...
IANAL however....
Your daily storage rate is way too low. It will cost you more to get what they owe you than you will get out of them.
Send them a letter changing the rate to £250 a day and stating payment terms of 30 days.
You have to be (legally) reasonable, so give them 14 or 28 days to get something sorted, after which the new rate will apply.
You should send them (snail mail and email) invoices every week reminding them of their ongoing commitment to paying you.
They may not pay you, in which case you have to go through small claims (Google it) or sue them to get the money they agreed to pay you (by not removing the vehicle after you gave them a reasonable time to comply) the former costs you time and effort the latter cost time effort and money.
In my experience, once invoices for significant sums start adding up to being a PITA for them, things will happen. Once the car is gone you have to decide if it is worth your time and effort to chase down the invoices. Hint - it probably isn't.
I got rid of incompetent bailiff companies this way (they kept buying a debt that someone had taken out using my address as theirs and the original loan company didn't check)
tl;dr - you have to make it worth their while to make you go away whilst being cool, collected and, above all, reasonable.
Judge is clearly mistaken.... Trump can just sign an executive order and, because the SCOTUS has said anything he does in post is legal, boom - AP are excluded.
Having thrown tea in Boston harbour to rid yourselves of tariffs and royalty, 200 years later, it sure looks like you have a king over there!
That's not how loans work for little people.... It totally is how loans work for oligarchs because the money they get from the loan provider is tax free so no income tax.
We, here in the UK, for all our faults, have waaaay fewer school shootings.... In fact way fewer shootings altogether (even when multiplied by ~5 for relative population size)
We used to use virtual box on windows with an immutable hard disk to boot the environment with storage, for persistence, elsewhere (usb for example) if required. Just used standard ubuntu for the guest distro.
Once you shut down the VM the vhd reverts to as installed. It's a bit painful distributing the system but can be done.
You can prevent ordinary users messing with the immutable setting as well if that is a concern.
Yeh, the oya got smudged/erased on the gold plate.
