Question BIOS unable to recognise any bootable usb ("no operating system found")


I have an all in one pc (sony vaio SVL24125CLB) that came with windows 10.
After dual booting windows and ubuntu for some time i decided that i didnt need windows any longer and deleted both windows 10 and ubuntu, replacing it with linux mint.
As i am quite a newbie i encountered some troubles with linux mint because of lack of GUI in some cases and other things.
The problem is that when i tried to execute windows 7 from a bootable usb drive it the bios didnt recognise it (giving the message "no operating system found". I started getting nervous (because now i really want to get rid of linux) and tried with different iso of windows 7, windows 10, resetting the bios to factory settings, different usb drives, etc. i also tried changing in the bios a setting from UEFI to LEGACY but it didnt work either.
i am sure that the problem is in my bios and not in anything else but i really dont know what to do.
any recommendations?

How sure are you that your USB device is bootable? Will it boot on other devices, and are those devices 32-bit or 64-bit devices?

thx for your answer
im sure that my usb devices are bootable because i have tries using both rufus and the windows iso creator. i didnt try booting in other devices though. all of my devices are 64bit and so are the ISOs

If it will boot there, but not on your Sony, then there is something wrong or incompatible at the Sony.
It could be the architecture, the USB device, or a setting.

Are you using 64-bit or 32-bit images? Jave you tested with other ISO images: live-cd images of Linux for example?

Have you tried a different USB slot?

i tried using different versions of windows (7 and 10). like two or three ISOs from each one, in 3 different pendrives. but they arent even recognised by the sony bios. this amazes me because i installed both ubuntu and linux mint with this method and th bootable usbs were read just fine at the moment.
i always use 64bit versions of the isos and dont have the possibility of using a live cd image, just usbs.
i didnt try with isos of linux because i want to get rid of it.

I use E2B (Easy 2 Boot) to load Linux, Windows, and other operating systems direct from the ISO images (including live-cd iso images) from a usb thumb drive. You might give something like it a try.

You should try another image to see if your usb hub/controller or port may have failed or changed. It may, for whatever reason, no longer support booting.

In some computers, in the BIOS, you can enable or disable a designated hot key to get a boot menu. If this hot key is enabled and the bootable USB is attached, upon booting the computer, when the Sony splash appears you can hit the designated hot key which is usually an "F" key like F10 or F11, and at this point the UEFI firmware interface should see the bootable USB and offer you to select it and boot it.

Since you mentioned you set BIOS to defaults, you may have disabled this feature
EDIT: If this option is not available in BIOS settings, it is automatically enabled, Google it to figure out which key is designated the hot key for the make and model of computer.

my pc doesnt have any hotkeys. to open the bios or access any other system settings you have to turn off the computer and press a button labeled "assist".
my problem is that my pc doesnt detect the bootable usbs

i will try but probably it wont work because none of my usb were recognised

i just found on internet that older computers cant read bootable usbs greater in storage that 4 gb. is it possible for this to be the explanation? when i installed linux mint a time ago i did it on a 4gb usb, same for ubuntu. maybe i should try with a disk? but i dont really know how to put a iso in a disk or what type of disk i need

4G USB keys are very cheap these days.
Why not find one 4G USB drive, format (perhaps only to 3.5G), and load it with E2B and the CorePlus image from tinycore? If it will boot that but not your larger Windows ISO that may verify that this is the issue. If this IS the issue you will then know your choices.

I far prefer Linux over Windows, and would just load up a version of Linux that would serve. To get Windows onto this device might take some effort.

Will this machine read a DVD? You could burn your Windows ISO to a DVD and load using that common and supported technique. If it cannot, then one of the remote load methods might serve. I would first check and see if the mfg support pages list a firmware upgrade that might provide you with a more capable BIOS and better options.

wpeckham, I would like to update the bios if it is possible. i am not in position to buy a virgin dvd or a new pendrive because i am far away from the nearest city right now. i believe that updating the bios to a newer one will solve the problem, but i have no idea of how to do that. what is the mfg? i visisted the support page of my computer in sony.com but it didnt mentioned how to update the bios.
also, what does remote load methods mean? thanks for your help
pd: i want windows back because as i am a newbie to linux i am very limited by it and cant do certain tasks. also windows supports a ton more software and has gui everywhere

In this case the MFG (manufacturer) is Sony. If the Sony support page for this device has nothing about updating firmware of bios, then it is likely that the device is one that cannot be updated by the user. I do not have one of these, so I cannot be sure.

I have loaded Windows over network, but I had time and resources to build a network install server using tftp, dhcpd, and use the network boot option of the hardware on hand. That is likely to be beyond most users, and if your device does not support network boot it may not work for you anyway. I would contact Sony support and ask if they have a windows reload procedure, and if you could aquire a copy of the documentation for that procedure. If they cannot or will not help you, I can only hope that someone here who has such a device and has faced a situation like yours will chime in.

BTW: while I PREFER working at the command line for many things, I have never run into a situation where Mint did not offer a gui solution. If you cannot load windows (and I still hope that with help from Sony you CAN), I would still consider loading a useful version of Linux. Your hardware investment is wasted if you do not load and run SOMETHING!

I believe this model is only sold in South America, but I have found sets of recovery CD/DVD for sale for this model.
Which means it is possible the OP can just burn the media to optical disks and it'll likely boot that form of media rather than USB drives.

EDIT: Also, when I've burned a ISO to USB with dd, the size of the USB appears same as the ISO, I've burned 355MB ISO to 8GB key and it was reported as only 355MB.
