"Something has gone seriously wrong," dual-boot systems warn after Microsoft update (Ars Technica)

Ars Technica coversa recent updatethat is causing problems for users with systems that dual-boot Windowsand Linux.

"Note that Windows says this update won't apply to systems thatdual-boot Windows and Linux," one frustrated person wrote. "Thisobviously isn't true, and likely depends on your system configurationand the distribution being run. It appears to have made some linux efishim bootloaders incompatible with microcrap efi bootloaders (that'swhy shifting from MS efi to 'other OS' in efi setup works). It appearsthat Mint has a shim version that MS SBAT doesn't recognize."

The reports indicate that multiple distributions, including Debian,Ubuntu, Linux Mint, Zorin OS, and Puppy Linux, are allaffected. Microsoft has yet to acknowledge the error publicly, explainhow it wasn't detected during testing, or provide technical guidanceto those affected. Company representatives didn't respond to an emailseeking answers.
