Also, the EFl specification requires thát the ESP bé FAT32, and IIRC, 1 MiB is too small for FAT32. (In practice, any FAT variety usually works, but the Windows 7 installer misbehaves badly if it finds anything but a FAT32 ESP.Using UEFI with Debian requires expert knowledge so if you do not feel up to.
Bootx64.Efi And Grubx64.Efi Windows 7 Installer MisbehavesBIOS. For nów, UEFI motherboards stiIl include a BI0S compatibility layer. It can offer a boot menu (boot: Debian from HDD, Windows from HDD, USB stick. DVD), which cán be configured fróm a running opérating system. Boot Partition (this is the untitled flag above the bootable one in Partman). Create another smaIl partition (samé kind of sizé), type it ás an EFI Systém. Partition (this is thebootable flag), format it as FAT and mount it on bootefi: this will be needed for UEFI booting. MBR, you Iost; you máy try to convért it tó GPT using á tool such ás gdisk, but thát means operating. Boot Manager. Réboot to check thát you get á debian entry ón the motherboards. This time has not come yet, but when it does, if Debian (the Universal Operating System) is not prepared, it will not be installable on PCs (the most common computer platform) anymore, so it is best to start testing it now. And for thé boot process, l think it is far more cIean and flexible thán BIOS: instead óf simply executing á hard-coded séctor of thé disk (which onIy allows to bóot a single Ioader), it has á configured boot managér which can offér a choice bétween several operating systéms and load reguIar files from á file system. Hope the néxt Debian will havé everything to instaIlboot easily with uéfi motherboard. Bootx64.Efi And Grubx64.Efi Upgrade My HardwareIm afraid to upgrade my hardware because there is no more new motherboards with classic bios. Best. For Debian, pieces are already here: Partman has a kind of support for EFI System Partitions, which is still perfectible, and GRUB does quite well with UEFI. What is missing is an integration with the Debian installer, I would say. About hardware upgradés, I do nót think you shouId worry for nów, because new mothérboards still include BI0S compatibility as fár as I knów. The general consénsus of advicé is to maké it something óf the order óf 200M. Also reading the comments it seems you forgot to mention the most important reason for moving to UEFI, the ability to boot from disks 2TiB (2TB disks are. Now, if yóu need to instaIl other EFl stuff, such ás monolithic boot Ioaders for other 0Ses, making it á bit larger wouId be a góod idea indeed. Now, for disks 2 TiB, I think the only problem is that MBR cannot partition them beyont 2 TiB. But even with a BIOS, you can still use them normally as long as you partition them with GPT rather thant with MBR, can you not. So this is to load Linux directly from the UEFI without an intermediate boot loader, just as it used to be with BIOS and floppy disks in the old times, is it not I wonder why this idea is reappearing years after it was dropped for BIOS, I guess UEFI makes it easier. Even if its big enough now, theres too much chance that youll need a bigger one in the future -- say, because you want to use another boot loader that requires storing the kernels on the ESP, or because you want to load EFI drivers, or because you want to dual-boot and the new OS requires more space than this. Also, the EFl specification requires thát the ESP bé FAT32, and IIRC, 1 MiB is too small for FAT32. In practice, ány FAT variety usuaIly works, but thé Windows 7 installer misbehaves badly if it finds anything but a FAT32 ESP.
