@ash said in Cannot find disk on system.:
hard disk can not support pxe boot?
The technical answer is they are not connected. PXE booting uses network adapter. If I understand you correctly the old hard drive is not seen by fos linux but new hard drive is? Is it using same technology? old hard drive == sata and new hard drive == sata? Or nvme and nvme? its very strange taht swapping hard drive with same type and now its found.
