The rationale is that we are not sure the consequence about integration an Linux boot into an existing - Windows setup. About consideration may not be necessary as ESP is + Windows setup. Above consideration may not be necessary as ESP is defined in UEFI specification as common places for OS loaders, which differentiate by their own paths. There's no concept that ESP is - specific to OS and be exclusive access from it. That would also lead to - several issues as two ESP is confusing in general to the firmware and - OS tools as they would assume only one single ESP as valid. Here are - some of the failure case illustrated. 1. Modify (or repair) Windows - boot configuration (BCD) on such system, two system partitions make - Windows quite unhappy. It completely ruined boot configuration until - hiding (by changing partition type) the one created by SUSE. + specific to OS and be exclusive access from it. + That would also lead to several issues as two ESP is confusing in + general to the firmware and OS tools as they would assume only one + single ESP as valid. + Here are some of the failure case illustrated. + 1.

Discussion: #1: Ludwig Nussel (lnussel) (2013-02-12 09:24:14) reusing the efi partition on my windows laptop worked just fine + #2: Karl Cheng (qantas94heavy) (2016-11-16 16:30:25) + Seems to work nowadays, installing openSUSE along with a pre-exsting + Windows install used the existing Windows EFI partition. -- openSUSE Feature: https://features.opensuse.org/314493
