Win loader 104/15/2024 Similarly if Arch is installed in BIOS/MBR or BIOS/GPT mode in one disk and Windows is installed in UEFI/GPT in another disk, the BIOS bootloader used by Arch cannot chainload UEFI installed Windows in the other disk. That is, if Arch is installed in UEFI/GPT or UEFI/MBR mode in one disk and Windows is installed in BIOS/MBR mode in another disk, the UEFI bootloader used by Arch cannot chainload the BIOS installed Windows in the other disk. Most of the linux bootloaders installed for one firmware type cannot launch or chainload bootloaders of the other firmware type. See Unified Extensible Firmware Interface#UEFI firmware bitness for more information and available workarounds. Due to lack of Legacy BIOS support in these systems, and the lack of 32-bit UEFI boot in Arch Official Install ISO ( FS#53182), the official install media cannot boot on these systems. Intel Atom System-on-Chip Tablets (Clover trail and Bay Trail) provide only IA32 UEFI firmware without Legacy BIOS (CSM) support (unlike most of the x86_64 UEFI systems), due to Microsoft Connected Standby Guidelines for OEMs. either go for UEFI/GPT boot or BIOS/MBR boot. In case where Windows and Linux dual boot from the same disk, it is advisable to follow the method used by Windows, ie. The Windows limitation should be considered if the user wishes to boot Windows and Linux from the same disk, since installation procedure of boot loader depends on the firmware type and disk partitioning configuration. Such a limitation is not enforced by the Linux kernel, but can depend on which boot loader is used and/or how the boot loader is configured. Tip: Windows 10 version 1703 and newer supports converting from BIOS/MBR to UEFI/GPT using MBR2GPT.EXE. Thus Windows only supports either UEFI/GPT boot or BIOS/MBR configuration. This is a limitation enforced by Windows Setup, and as of April 2014 there is no officially (Microsoft) supported way of installing Windows in UEFI/MBR or BIOS/GPT configuration. If Windows is booted in Legacy BIOS mode, it can be installed only to an MBR disk. if Windows is booted in UEFI mode, it can be installed only to a GPT disk. In general, Windows forces type of partitioning depending on the firmware mode used, i.e. If the value is Legacy, Windows boots in BIOS/MBR mode.
