No OS found on old IBM computer

Sorry, I am confused! Do you keep trying to install 64bit Fedora 32 onto a machine without 64bit CPU? I am hoping you are not.
For CentOS, did you download CentOS-7-i386-Minimal-2003.iso? Because this is the only one that will work on you machine.
I think that the best thing that you could do at this point is to post the exact model of your CPU, because even Pentium 4 became 64bit at Prescott architecture stepping N0 and you might have 64bit support actually. Go to the BIOS and read/post the exact model of the CPU. Or run Windows and CPU-Z CPUID.

I have an Intel Pentium 4 531 which has a 64 bit architecture. It should be working but is giving me problems with OS not booting from a usb even with usb as the first priority in the boot order.

Guys I am having a strange problem. I tried to install Fedora 32 server edition on a 32 bit pentium 4 and after my computer would say their is no OS after exhausting my options and self I looked for help on this website. So I went to install CentOs 7 and when I plugged it in the first time from a usb after hitting f12 at boot sequence the machine loaded into CentOs installation screen. I was installing the netinstall version and it was having problems installing from the net. I then put a minimal version of CentOs on the stick and this same computer with an i386 booted up Fedora 32 from the previous install attempts. It will not load CentOs on the USB. I finally got onto the terminal for the Fedora 32 server edition after having to change the root password because it would not work. Turns out after many attempts to get past the password and changing the password it would not change and after managing to get past the password terminal I am on the localhost login screen for Fedora 32 which should not have ran if the information I have found is correct from the help on a separate page here.

Fedora 32 is NOT designed for use on a 32 bit system (F31 and earlier could use 32 bit).
You should get an install image for a 32 bit OS, install it and see what happens.

When you boot from the live USB (which may require use of the bios) first use the fdisk utility to make certain the old failed install is wiped out and a new MBR partition table is created, then do the install of the 32 bit OS. It should work.
I suspect the partition table got modified to GPT which will not work with a 32 bit OS. I believe F32 is UEFI boot only.


Make sure your Centos7 image is the 32bit version. (should say i386 in the image.)

Try setting your bios to boot from the USB by default.

Then do as @computersavvy says. Use a partition utility to delete everything on the disk, then create a new MBR (sometimes referred to as MSDOS) partition scheme. Then format your partitions as desired. Hint: An MBR scheme does not have an EFI partition, that’s how you know you got the correct layout.

You should be able to get CentOS installed after that.

You have now started 2 threads on this. Help us help you and keep this in one thread.


I’m still confused if OP has 32bit or 64bit architecture, on the other thread they are now saying it is a 64 bit machine. :hot_face:

In any case, an admin should merge the two threads.

@aughestinioperosis. I don’t agree with @amoses200 statement. There is no major change from 4.x to 5.x, it just got named version 5 because large numbers behind the ‘4.’ are too inconvenient for kernel devs. Could have easily been 4.22, kernel versioning is not feature-based!
Fedora is cutting edge, which doesn’t mean it doesn’t run on old hardware. The lightweight spins are made for exactly that purpose. Moreover, rest assured, if kernel 4 series supported an x86 chip from the early 2000’s, kernel 5 will supported equally well (or better). (This is different for exotic hardware, but not for Pentium 4)

Can we now assume that this is true? Otherwise, you wouldn’t be able to install any Fedora. Apparently you did successfully install Fedora but faced some problems. The solution for that is not to go for CentOS 32 bit.
Now, for each problem please let’s discuss separately (in separate threads or topics as they call them).

Where are we at and what is the single issue that we will help you solve here? Also, please provide precise and distinct information, or we are guessing in the blind (32 vs 64 / install problem vs. boot problem / login problem / password reset / iso to usb / …).

Thanks and welcome @aughestinioperosis to the Fedora Community. If you’ve not had a chance yet, please look at the #start-here category. It has some very useful information on using the forum and tips on Fedora usage.

By the way, if you decide to continue your journey with Centos, their support forum is here:


Interesting. I’ll take notes and cut that part out of my comment since it’s wrong. Sorry about that.

The OP is still better off by using a previous version of Fedora. 26 supports modern TLS, so it is a good candidate. Every next version becomes heavier and heavier, and his P4 Prescott is unlikely to cope. Also, if he is constrained on RAM, a 32-bit Fedora 25 is going to be more compact due to 1/2 word size in its program code.

No! Running an unsupported F25 or F26 cannot be recommended, at all.

Please, @aughestinioperosis don’t do that!

Lxqt or Xfce doesn’t need that much RAM, even on F32.

Unsupported Fedora versions will have security holes due to outdated software.
