"content": "While Microsoft claims \"The SBAT value is not applied to dual-boot systems that boot both Windows and Linux\", is this always true?\n\nIf I have a Windows system that I sometimes boot into Linux from a USB drive, will Windows Update be able to detect this? Of course not. What if I use some sort of other unexpected \"dual boot\" mechanism? Will Windows Update detect this? Maybe.\n\nWith the August Microsoft SBAT update, SecureBoot will fail to boot any EFI module that specifies anything less than shim,4\n\nWhat does the Ubuntu 24.04 ISO specify?\nshim,2\n\nThis is why the Ubuntu 24.04 (and others) ISO won't boot on a SecureBoot system that has the August SBAT updates that Microsoft pushed out.\nhttps://media.infosec.exchange/infosec.exchange/media_attachments/files/113/001/281/889/026/407/original/e32ef12a5ab03e40.png\nhttps://media.infosec.exchange/infosec.exchange/media_attachments/files/113/001/282/797/827/295/original/588517c6e8a08965.png\nhttps://media.infosec.exchange/infosec.exchange/media_attachments/files/113/001/284/228/996/244/original/52140bee3681d5d4.png\nhttps://media.infosec.exchange/infosec.exchange/media_attachments/files/113/001/284/929/773/467/original/20fccc6ba58e56b2.png\n",
