Access the BIOS via the command prompt. Solved

Question

Hello,  I have a question (possibly twisted but here goes): is it possible to access the BIOS through the command prompt in order to install a new Windows via a bootable USB stick knowing that:  1- I can no longer access my home desktop due to a configuration issue with an update. I can only access the command prompt in safe mode.  2- I was unable to repair my Windows using the Microsoft tool and I cannot perform a system restore. (I know, it sucks!)  3- I prepared a bootable USB stick using the Microsoft Store tool and when I press F2 at startup, I get a black screen that looks nothing like the usual BIOS interface (no boot button or any other buttons for that matter!) and the only option is to boot into Windows!  Is there any hope :D ??? Thanks in advance for your answers  Configuration: Windows XP / Chrome 49.0.2623.112 -- Wondering...

You close the cmd. You open it again. You type diskpart Confirm with enter. You type list disk Confirm with enter. You type list volume Confirm with enter. You type list partition Confirm with enter. You locate your USB drive (not a number, but we need a letter, for example F:) Once you’ve found your letter, you type  select volume E (you adjust the letter to that of your USB drive) Confirm with enter. You type cd setup.exe Confirm with enter. Tell me what it does.  Gaming is not a crime. Toshiba P870 - Dual Boot w8.1.3/w10 - i7 3630qm - 8 GB Dual Channel - Nvidia GT 630M 4 GB

hello.  As you say you have access to the command prompt. Why don't you try this first.  Type rstrui.exe  and validate with the enter key.  And it is impossible to access the BIOS via cmd...  What do you have on your USB key?? The Windows 7 ISO??  -- Gaming is not a crime. Toshiba P870 - Dual Boot w8.1.3/w10 - i7 3630qm - 8 Go Dual Channel - Nvidia GT 630M 4 Go

Hello For your first maneuver, I realize (after trying it) that it's a command for a system restore; however, I explained that I do not have a backup on my PC (it's new)  For your question, yes, it is the ISO of a new Windows 7 that I want to install.  I ask my question once again: how to access the BIOS either via the command prompt or through any other means?  Here is the image of the page I get after trying all the "F" keys   Thank you.  Wondering...

ha I thought the restoration was bugging, I didn't think you didn't have it..  so I find it surprising that F2 brings you to this screen (the advanced options of w7)  if no "F" key works, just try Escape. it's often the right key to access the BIOS.  but accessing the BIOS is one thing. being sure that your key is bootable is another. because F12 or F10 (it varies by brand) will boot your USB key, if that's not the case, then the problem lies with your poorly made key..  -- Gaming is not a crime.

To begin with: escape gives me the same result.  By (re)typing F10, it gave me this new screen:    Regarding the USB key, we can only be sure after having tried at least once. I followed the instructions on this forum using the Microsoft Store tool: everything should be fine in principle.  So my question remains: how to access the BIOS???  Wondering...

there is a serious problem...  if no key allows you to access the bios, then that's not normal. so let's go back to the order of things.  brand and exact model of the pc..?? do you have the pc manual.?? if yes, you will need to read it and find the correct key. if this key is found and you still cannot access the bios, then the ultimate solution remains, remove the hard drive from the pc, and start the pc, then you will automatically enter the bios. you can plug in your usb drive, set it as the first boot option. turn off the pc. put the hard drive back in the machine. and start the installation. if even after removing the hard drive, you find yourself on a black screen with no bios, then that smells like a failure or hardware malfunction....  -- Gaming is not a crime.

I'm going to try this method, but in the meantime, will formatting the "C" partition of my hard drive using the command prompt not help me achieve the same result?  But anyway, regarding your first question, I'm not in France and the PC in question is from a brand you've probably never heard of; so the manual and customer service are not great :D. Plus, it's an All In One PC....... anyway  My top priority: find that elusive key.  Thanks for your efforts... keep in touch :)  Wondering...

darkleopard · Answer

It's a double-edged sword. That is to say, if you format your C: drive, there is no guarantee that you can access the BIOS and if, once formatted, you can't boot from your USB drive, you'll understand—you'll have a PC without an operating system, without access to the BIOS, therefore unusable but you surely have a recovery partition, which is also accessible via a key What really bothers me is the BIOS inaccessible via the F.x keys. The PC looks brand new; from the pictures, I can see it has a protective plastic If so, you can perhaps take it back to the store, explain the problem to them, and even invoke your warranty. Unless the seller knows the mysterious key to access this mysterious BIOS...  -- Gaming is not a crime. Toshiba P870 - Dual Boot w8.1.3/w10 - i7 3630qm - 8 Go Dual Channel - Nvidia GT 630M 4 Go

Hello  I'm getting involved in the conversation ....  You can't access the BIOS from the command prompt, it's not meant for that.  You need to access it with a key, at startup ...  However, what you might be able to do is: go to the command prompt, with the USB drive plugged in. navigate to the USB drive, and type setup.exe This is to launch the Windows setup. What does it give?   -- There are 3 types of people: those who can count and those who can't.

darkleopard I contacted customer service and I'm waiting for a response   Hello phil2k  just tell me how to access my USB key via the command prompt and I'll give it a try  Thank you all  -- Wondering...

Re  I'm here and it is indeed 'disk 1'  Wondering...

darkleopard · Answer

So now you type select disk 1 Press Enter to validate  There, you either type setup.exe Press Enter to validate.  I don't know if it's going to work. You can also try typing start setup.exe Press Enter to validate. See if it works. Personally, I've never done it this way, so I'm experimenting a bit ^^  -- Gaming is not a crime.

Nothing at all :/... it gives me a list of different commands for different operations on the hard drive.  I have to wait until tomorrow to get a response regarding the key; but in the meantime, if you have other maneuvers, I'm all ears :)  -- Wondering...

phil2k · Answer

I slightly correct the procedure:  diskpart  list volume  locate the letter corresponding to the drive (for example F:) exit   at the prompt, type  F: this will display F:> setup.exe -- There are 3 types of people: those who can count and those who cannot.

darkleopard, skipping the "list partition" step which yields nothing, the other steps give me the same result as before: a command list  phil2k, for your manipulation: it yields nothing (an unrecognized command)  I was able to recover my system thanks to the method from "lacharpante"; I thank him once again.  I will try again to reinstall a new Windows and see if I can access the bios or not. I'll keep you updated.  Thanks again, guys :)  Wondering...

Rasta_Pocchollas · Answer

I tried again and I'm still getting the same screens. I will make a trip to the seller tomorrow to see what it looks like on a similar model, but otherwise I have to wait for a response from the after-sales service.  In short, I will keep you updated.  Thank you and have a nice end of the day.  -- Wondering...

It's good, it's finally working with the "delete" key and I don't know if the system recovery had anything to do with it.  Anyway, thanks to everyone for contributing :)  Special thanks to "darkleopard" -- Wondering...

Indeed, I hadn't thought of the Supp key; it's so rarely used nowadays for accessing the BIOS...  Glad your problem is resolved. We all struggled a bit, after all ;)  Good luck to you @++  -- Gaming is not a crime. Toshiba P870 - Dual Boot w8.1.3/w10 - i7 3630qm - 8 Go Dual Channel - Nvidia GT 630M 4 Go

Good evening, is it possible to boot from an esd-usb Windows from the command prompt? Yes, ask Tontonsebastien and Ikewdu  I managed to boot for someone on ccm their esd-usb iso Windows 8 device on a Windows 8 UEFI PC with the help of a Dart cd-rom that he had created His system partition was corrupted "RAW" and he no longer had access to Windows recovery environment, so command prompt  Dart requested by Ikewdu, I took advantage of the options in Dart Witnesses: Ikewdu and Tontonsebastien, they will surely recognize me ;)
