Convert Windows boot from BIOS to UEFI without decrypting Bitlocker

I wanted to convert an MBR/BIOS boot drive to GPT/UEFI, but without needing to decrypt and then re-encrypt Bitlocker. Mainly because I am lazy. This worked, but I’ll warn that the advice to decrypt completely first is without any doubt the safest way to go. Follow the instructions for converting from BIOS to UEFI boot. […]

The admin user on JunOS SPACE, which is used for ssh / root access, has a default password expiry of 70 days. This may not be desired. NB: An upgrade of the JunOS SPACE platform will set the admin password expiry to the default of 70 days again. To avoid the admin user password being […]

Recover Juniper SRX from failed boot

[Edit 2018-05-14] This article describes how to boot into the backup partition from u-boot. If your primary still boots, try “request system reboot media internal” (Branch SRX) or “request system reboot media disk” (High-End SRX) instead. Thanks to batdosi for this. They also mention sysctl from shell, that may be another way to set the […]

It installs easily on Windows, pre-compiled or compiled from source, with good […]
