I just installed Ubuntu 12.04 32-bit on an ASUS Laptop and wanted to install it in another one, the ASUS A55V.
After booting the laptop and setting up Windows 7 (I unfortunately cannot wipe out Windows), and creating one extra partition to install Ubuntu there, when I reboot from USB and launch Ubuntu installation, it doesn't recognize any partition on /dev/sda, but shows the whole disk as unpartitioned. I guess this is due to UEFI, but I don't know how I can make Ubuntu see the partitions created by Windows. Or any workaround for this to be able to install Ubuntu on /dev/sda.
Thanks in advance
