C'est la vie!
I hate it when I make coasters - that hole n the middle doesn't protect my fine Ikea furniture very well.
I prefer to use a CD - nasties can't write to them (but neither can you at the moment , but sure, you can put Bitdefender Rescue on a Flash drive. A CD-R is large enough - but try the flash dirve method
See: How to create a Bitdefender Rescue CD
Creating a Bitdefender Rescue CD on a USB flash drive
When you cannot write a CD/DVD, you can use a USB flash drive. Bitdefender recommends Stickifier, a free open-source tool that creates a bootable Rescue CD on a USB flash.
I've never used Stickifer
The only things I see worth mentioning are
Select an existing ISO image - the Bitdefender ISO you already have
The USB must be FAT32 formatted
<!> and all data will be erased.
Let me know if you get stuck using Stickifier
Please don't apologize. Everyone here volunteers because they enjoy helping people with technological issues.
If I give up, and I rarely do, I'll raise a white flag and suggest a clean install. I didn't think the issue warranted a clean install when I started helping, and the issues still aren't bad. There will always be some residual cleanup after malware remediation. Bitdeferende was probably the last scan , but HW got in the way
