Hi,
we're working with the Universal USB Installer's author to fix
https://labs.riseup.net/code/issues/7378 ("Universal USB Installer
creates unbootable devices").
If you have access to a Windows machine, please consider following
these steps:
1. Save the attachment on your disk (the UUI's author tells me it's
a snapshot of UUI that adds the feature we need)
2. Rename it to .exe
3. Download the most recent ISO image from
http://nightly.tails.boum.org/build_Tails_ISO_experimental/
4. Use the aforementioned .exe to install the ISO you've just
downloaded to a USB stick.
5. Try booting off that USB stick.
6. Report success or failure (in the latter case, it's helpful to
describe in full details the exact behavior, including full error
messages if any).
Thanks!
Cheers,
