I received a message saying: An operating system wasn't found, please unplug anything without one.
Hey, as the title says, I got this message: "an operating system wasnt found. Try disconnecting any device that dont contain an operating system." I was using my PC normally, just browsing chatGPT. I wanted to do a calculation and noticed when pulling up the calculator, the program almost wouldn't start, and then everything else got really slow. I force shut down the PC, and when trying to start it up that message came back. I don't really know what to do, and I am pretty good with my hands. I am reading for multiple exams, so I am often at my laptop and ready to check in here and take some action! It's windows 10 with a ROG MAXIMUS XI HERO (WI-FI) Motherboard - 2x NVMe Samssung m2
Here are the full specs, including the power supply make and model (or part number). Also, how old the PSU is, and was it bought new or used/refurbished? Either the OS got corrupted, or the drive is dead. Just boot up to BIOS and check if the OS drive shows up and lists as one of your boot options (it should be first).
Just a side note: When a program is running it lives in RAM (except possibly if swap/virtual memory is used). Even if the disk were to die the program actually in RAM will usually work just fine until disk access is needed. Having the calculator fail could be a disk failure. Not finding the o/s on boot tends to back up that idea. What @Aeacus mentions about going into the BIOS is a pretty valuable suggestion because the BIOS can see disks as a whole, and not just files on a filesystem inside of a partition. If the disk does show up, then it might still be failing, but you stand a chance. If the BIOS itself for example had corrupted (maybe the button battery is low), then it might be as simple as setting the BIOS up again. While power is on the BIOS won't corrupt just from a battery dying, but when power goes off it might.
1. If your BIOS is messed up, your computer won't finish checking itself (POST), and you will never see any error messages or pictures about it. 2. A dead CMOS battery doesn't actually damage the BIOS. It just means that when your PC isn't plugged in, the settings you saved won't stay there until power comes back on. Your computer can still work fine without a CMOS battery inside. But this might annoy you because all those custom settings get wiped clean to their default state, and it makes the clock stop counting (which is not a big problem now since Windows gets its time from the internet after it boots up).
I bought a power supply that is about four or five years old, and I'm using an Intel Core i9-9900K CPU on a motherboard named ROG Maximus XI Hero wi-fi. The memory sticks are Corsair Vengeance LPX DDR4-3200 C16 BK DC, with 16GB of RAM, while the graphics card is GIGABYTE GeForce RTX 2060 OC with 6GB GDDR6 and a storage drive is a Samsung 970 EVO Plus SSD M.2 in an M.2 2280 slot holding 1TB. I have another Samsung 970 EVO Plus SSD M.2 in a 500Gb slot, but the power supply (PSDU) is a corsair cx750. My operating system is Windows 10 Home. The BIOS seems to see both M.2 drives, and I'm pretty sure (probably ninety-five percent) that Windows was installed on the five-hundred-gigabyte drive instead of the one terabyte drive. When I start up my computer, Boot Option Priority #1 points to the five-hundred-gigabyte drive. Even if I try to force a boot from the other drive using the "Boot override" feature, nothing changes. Also, under Boot Option Priorities, there isn't an option to select the one terabyte drive as the first choice; only the five-hundred-gigabyte drive (or the disabled one) is listed. I'm also wondering what the settings should be for CSM if we talk about both UEFI and Legacy modes.
You have access to another computer, you can download a bootable USB stick using this link: https://www.majorgeeks.com/files/details...4_bit.html This tool has many utilities to check disks and the system and even fix some problems.
When Win was installed, were both drives connected to the system or only one? Since when both were connected, it could be that boot manager lives on 2nd drive and it might got corrupted. Hence why not able to boot to OS. Then, at least, there is some life in the SSDs. Maybe enough for repair the OS or format the drive for clean Win install. Or maybe not. Unknown at this point. Best course of action; 1. Any empty drive (e.g SATA SSD will do). 2. Disconnect both M.2 drives. 3. Install the new, clean Win to the empty drive. 4. Make sure you can boot to OS. 5. If successful, power down, connect both M.2 drives back to system, make sure in BIOS that the new installation (SATA SSD) is 1st boot priority. 6. Boot to OS and run checks on both of your M.2 drives (e.g Samsung Magician). This way, all the data you have in M.2 drives is kept safe, since both drives would then act as data drives. And you can copy/paste your personal data over. This method would keep both M.2 drives safe, just in case there was an OS drive failure. While giving you good grounds for data recovery. Now, it is possible that due to drive failure (if drive did fail), BIOS will see it, but Device Manager will not. And once in the OS, you can't access the drive. In this case, your options are limited. There is option to recover personal data from failed drive (albeit expensive). But if there is no need to recover data from failed drive, you can just RMA the drive and get a new one where to install OS 3rd time around (2nd time around would be the SATA SSD for possible data recovery/drives diagnostics).
1. How about a flash drive, will that do? It seems like there is something I cant quite figure out. I am now trying to do a clean Windows 11 install on the 1TB M.2, but the installation keeps failing. - A sidenote: When im about to do the Win 11 install I can sort of "browse" into both M.2(when they are both plugged in ofc). And there I can see which folders I have on them etc. I don't know if that says anything of help. I deleted the partition on the Disk 1 (which is atm. the 1TB M.2), trying to proceed with "next" with the installation I get the error message "There is an error selecting this partition for install. choose another partition or refresh choice.". I saw a video going into the CMD, selecting the Disk 1 and typing in "clean", it was successful and after pressing update in the installation window the error message persists. Do my BIOS settings need to be at something specific such as "UEFI ONLY" or in the secure boot OS Type "Other OS" or "Windows UEFI mode". I am quite confused, but it seems like I did delete everything from the 1TB M.2 drive, which is ok - I do however want to try and keep everything from the 500Gb drive.
Here are some facts about UPS batteries: A backup power unit that keeps a PC running when the main wall power goes out comes in two types. The first kind only works if there is no under-voltage (the cheaper one). The second kind can even work while there is under-voltage instead of total power cut-off. The worst mistake is not total power loss, but rather "brownout" (under-voltage). During this state, everything looks normal on the outside, but small errors called bit flips start happening inside. The BIOS runs like its own little microcomputer and controls things step by step even when simple. It usually has a basic driver for memory and hard drives. If the BIOS is working well and the battery is dead but power keeps coming through, nobody will notice the problem. However, if total power completely fails, it's also unlikely the computer won't start up at all, though it might reach the BIOS screen depending on how the BIOS is built. The real issue is just like that "brownout" or under-voltage described earlier. Some parts of the firmware can get corrupted while other parts keep working fine. It is possible for one piece of hardware to fail during these conditions, which means you would need to restart the system to fix it. This happens because if a tiny bit flips, turning power back on won't flip that specific bit back to what it should be. While this isn't common and might not seem rare, it's actually possible enough that checking by resetting the BIOS to its default settings is worth doing quickly.
Well, you can't just put Windows on a USB stick and then run it from there. The flash drive is only used to make the Windows installation files, so you must put those files on a real hard drive or other storage. For more details on how to do this, check out this link: https://forums. Windows 11 only works with UEFI mode. Windows 10 can work fine in Legacy mode too. So make sure you turn on UEFI. Also, secure boot has to be turned on before installing Windows 11 (you can turn it off later if you need to). When it comes to the power supply unit (UPS), there are actually more choices than the two types you mentioned. Based on your description, you seem to mean a UPS that doesn't have an automatic voltage regulator (AVR) and is likely using standby mode, versus one with an AVR that uses line-interactive mode. If you add dual-conversion-on-line and delta-conversion-on-line models to this list, then for those units, the brownout issue really isn't a problem at all because all the power from the battery goes directly to the PC. The main power just helps recharge the battery as it drains. Nobody should buy a UPS without an AVR unless it is designed specifically for on-line mode. And in my opinion, every computer needs a backup power unit (UPS). I actually have two PCs and I have one UPS for each one. I've never seen a PC with a corrupted BIOS because the BIOS contains specific instructions that run when the system powers up. During this process called POST, if something fails inside the hardware, the computer won't start up correctly and you won't even be able to see an image or enter the BIOS menu at all. Well, yeah, it doesn't take much time. But resetting the BIOS after every single hardware failure isn't going to fix everything. It is far more likely that one of the individual components broke than if the BIOS got corrupted.
