Ubuntu does support MBR. It is unclear what is the problem. If you boot Ubuntu LiveUSB in a legacy mode, it will install easily. Ubuntu can be installed in UEFI mode too on MBR.

It doesn't matter what you selected to create a LiveUSB. You an always boot in legacy mode using bios menu if bios allows it. BTW I am writing from Ubuntu 22.04 installed on MBR.

Microsoft has required vendors to install Windows in UEFI/gpt since Windows 8 released. If system is that old you may want a lighter weight flavor of Ubuntu. https://ubuntu.com/download/flavours Light weight flavors: Lubuntu, xubuntu, Ubuntu MATE, Budgie

Some machines allow booting in both modes, with one preferred. The Ubuntu install media has both boot methods, so maybe your machine is set to prefer UEFI over MSDOS (and your hard disk has no UEFI partition, so MSDOS is used). Change the preference in the BIOS/UEFI settings. Also, MDSOS partitioning only allows 4 primary partitions. The Ubuntu install may go into an extended partition on logical partitions (extended is counted as a primary, but allow sub-partitions).

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
