 **RHEL installation notes**
 
 * Azure does not support the VHDX format. Azure supports only fixed VHD. You can use Hyper-V Manager to convert the disk to VHD format, or you can use the convert-vhd cmdlet. If you use VirtualBox, select **Fixed size** as opposed to the default dynamically allocated option when you create the disk.
-* Azure supports only generation 1 virtual machines. You can convert a generation 1 virtual machine from VHDX to the VHD file format and from dynamically expanding to a fixed-size disk. You can't change a virtual machine's generation. For more information, see [Should I create a generation 1 or 2 virtual machine in Hyper-V?](https://technet.microsoft.com/windows-server-docs/compute/hyper-v/plan/should-i-create-a-generation-1-or-2-virtual-machine-in-hyper-v).
+* Azure supports Gen1 (BIOS boot) & Gen2 (UEFI boot) Virtual machines.
 * The maximum size that's allowed for the VHD is 1,023 GB.
 * Logical Volume Manager (LVM) is supported and may be used on the OS disk or data disks in Azure virtual machines. However, in general it is recommended to use standard partitions on the OS disk rather than LVM. This practice will avoid LVM name conflicts with cloned virtual machines, particularly if you ever need to attach an operating system disk to another identical virtual machine for troubleshooting. See also  [LVM](configure-lvm.md?toc=%2fazure%2fvirtual-machines%2flinux%2ftoc.json) and [RAID](configure-raid.md?toc=%2fazure%2fvirtual-machines%2flinux%2ftoc.json) documentation.
 * Kernel support for mounting Universal Disk Format (UDF) file systems is required. At first boot on Azure, the UDF-formatted media that is attached to the guest passes the provisioning configuration to the Linux virtual machine. The Azure Linux Agent must be able to mount the UDF file system to read its configuration and provision the virtual machine.
