Ubuntu won't install

Solved

Hello, I recently acquired an old computer, which I must clarify was assembled and therefore was not purchased as a complete unit.

This machine is not exactly recent and tends to lag, so wanting to use it for storage and being rather curious to explore Linux, I decided to install Ubuntu.
Originally, the PC was running XP.

So let me explain the problem: the installation goes smoothly and everything seems fine. The problem arises when I restart the PC, and it boots not into Linux but into XP Oo
The most surprising thing is that I did not install it in dual boot, and during the installation, I chose to delete XP to be replaced by Ubuntu, so no partitions were made.
I do not understand why instead of booting into Linux, it boots into XP when it is supposed to no longer be installed.

Thank you in advance for your help.

Hello,
On one hand, Ubuntu on an old XP PC may not be the best choice. I would suggest installing a distribution with a lighter desktop (xfce or lxde). If you want to stay within the Ubuntu family, Xubuntu or Lubuntu would work just fine. Note that Linux is not limited to Ubuntu; there are dozens of other Linux distributions that may suit your hardware better (often better than Ubuntu).

On the other hand, if your PC boots into XP, it's because you have installed Linux alongside Windows (probably without your knowledge). In general, it’s better to avoid using the automatic installation, which is not transparent at all and can sometimes lead to unpleasant surprises. Prefer an installation using the "Something else" option when choosing the installation type; this way, you can keep control over what is really happening.

To solve your problem, I see no other solution but to reinstall. When the installer reaches the partition selection step, delete all existing partitions and create 3 partitions yourself: one with a maximum of about 20 GB for the system root (/), another of about 2 GB for swap, and a third with all the remaining space for /home.
Choose ext4 as the format for / and /home.
Install grub (the boot manager) in the MBR of the disk (sda) and definitely not in the partition (sda1), and it should work.
Good luck!

Hello,

The simplest thing is to delete all the partitions on the disk before installing.

So boot from the CD (or USB stick) in live mode, with GParted, the partition editor, to delete all the partitions on the disk.

Then redo the installation.

Best regards

Hi,

Maybe it would be good to know the exact configuration of the PC (CPU, RAM, GPU) beforehand, because generally, Ubuntu (latest version: 14.04) is not really made for low-end computers ;-(

Thank you for all your advice, it was very helpful to me ;)
And thank you to you jns55, I followed what you advised me to do and I created the partitions.
And it successfully removed XP.
