unable to install Ubuntu 22.04

[Guillaume Tetart]

Hi sir,
my computer model is the following :
HP xw4400-Workstation
Bios 2.07 - no UEFI !
Processor : Core 2 duo
8Gb of RAM memory
two 500Gb HDD in hardware Raid-1 configuration, displayed as bootable ; I need performance (Raid-0) redundancy (Raid-1), so I don't want a soft Raid !

The partitions are the following :
SWAP 2048Mb
BiosGrub 16Mb
/ 245945Mb
/tmp 2048Mb
/home 250042Mb

But the problem is always the same : the installation always hangs when installing the bootstrap on the dedicated partition ! ...

Best regards,
