I have root on my computer but I can't edit the BIOS and so I can't boot from a USB/CD etc. I could plug in a new hard drive but I would like to know if I can install and boot off a new install of Ubuntu without doing that.




Is it possible to install a new version of Ubuntu and edit grub to
make it point to it somehow without have to boot off an external device?





ubuntu boot

  • @imbuedHope Sadly not. In fact I tried that first to upgrade from 14 to 16 and it completely destroyed my install which is why I would like to install a fresh version of ubuntu now.

What do you mean you cant edit the BIOS?
- Are you not sure how, or do you have SecureBoot enabled??



The only way I can think of that you wouldnt be able to get into the BIOS would be if there was an admin password set on the machine which could be wiped by resetting CMOS.

  • There is an admin password indeed. I suppose I could open it up and reset the CMOS but I would be interested to know if this can be avoided.
    – Lembik

  • All you have to do to reset the CMOS is jump the correct pins, I would definitely research it first if you're not sure how to do it on that particular machine. The quickest and easiest way is to reseat the CMOS battery.

  • Thanks. In the worst case I will open it up and see if I can look up the motherboard to see how to do that.

  • You can usually find the correct documentation in the manufacturer guides on their support sites. Looking up the MoBo info will probably take you down a rabbit hole you dont want to go down, when checking the manufacturer directly would yield the best and quickest results. Good luck!

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this
