I have DELL inspiron 7560 which has pre installed with windows. I want to dual boot it with Ubuntu. I have created a booatable device. But on startup it is not showing USB drive to install Ubuntu.
What tool/utility did you use to create the bootable USB?
If you did use Rufus to create your USB, after setting up the USB and clicking "START", select "Write in DD Image Mode" instead of "Write in ISO Image Mode".
I have found that writing in ISO Image Mode tends to make bootable Linux USB's to not appear or work properly.
Computers nowadays use UEFI by default, so make sure that your bootable USB is formatted as GPT. Otherwise if you create a bootable USB with MBR instead of GPT, it may not be visible.
Make sure that you are going into either the F12 boot menu in the BIOS, or set the boot order priority in the BIOS, or else you won't be able to boot from the USB drive.

I notice that a virtualized macOS can write to a USB pen drive both using the Finder or the Terminal. A program made by me instead (FileManager or NSFileManager)can't but on the host works as expected. Why?
Just curious what format the drive is running. I have noticed exFat makes a difference.
The PC is Windows. I wanted the ubuntu environment, I put the ubuntu iso file on the USB. After that, if I try to restart and start ubuntu, I get an error like the following.
Like this error
The details of the error are the two statements below.(initramfs) Unable to find a medium containing a live file system[figure ex.) 135.392108] usb 3-4: device descriptor ewad / all, error -110I tried variously, but it was useless. (I tried BIOS etc. but it was useless.What I want to do is to have Ubuntu portable on the USB. However, I want to prevent any Windows from being broken.I do not know the meaning of 2.0 / 3.0 on the USB drive side and socket side.The one that I use is USB 3.0.Ubuntu version is 18.04.2. The iso. file was loaded with Universal-USB-installer.I tried both UEFI and LEGACY mode with BOOT on the BIOS screen, but it was useless.
Device: MacBook Pro Mid 2017 with High Sierra
In order to install Windows on MacBook, bootcamp creates 7.4G partition that acts as a bootable install disk for windows(called OSXRESERVED). Note that this is in addition to BOOTCAMP partition that windows is going to be installed at.
Bootcamp, modifies windows ISO with addition of drivers to make the keyboard and touch pad work during install. It also add necessary drivers to be installed.
Here is the issue:
I created a USB image of 7.4G installer partition(OSXRESERVED); which has all the modifications + boot camp drivers. I booted off of the USB and could install windows with no issue. All drivers get installed after first login and everything seems to be operational; Except for keyboard back-light and keyboard touch bar. Re-installing boot camp drivers do not fix the issue. Under Device Manager in Windows, I do not see touch bar or unknown device.
Since Bootcamp creates the install partition and I have a USB bootable copy of that, I was expecting this be similar to boot camp assisted install (which touch bar and keyboard back light work under).
I am not sure what might be the problem or how I can fix it.
Thanks in advance.
I think I figured out the answer:
Warning: If you're not going to keep MacOS, either back up the EFI System Partition (and restore its contents to the new ESP after installation) or leave it intact (i.e. don't do a full disk install, but just use the space after the ESP). This partition (it's the first one) contains drivers/firmware/etc needed by Apple's EFI loader during boot, in particular to initialize the Touchbar.
I have a Mac running VirtualBox with a Win 8.1 client VM.
I have a program to run in the VM that requires access to a USB dongle — note, not a storage device! Sadly, whenever the Mac restarts it grabs the dongle, so before the VM can use it remote hands must physically remove it from the Mac and plug it in again.
Is there some way to programmatically eject (virtually, not physically of course) such a USB device from the Mac so that the VM can then take over ownership? I'll be happy to dig into I/O Kit or whatever Framework in Cocoa may be needed to accomplish this. I'd just rather not start if it's obviously impossible.
This question and answer is similar to what I'm looking for, but Step 6 is "Remove the USB device from your physical machine." I'm trying to avoid fiddling with the physical hardware by hand so that I can automate the process.
Like the question says: can you put some files on a usb, that run when you plug it in to your computer? maybe make a mini OS that you launch from bios? I have to be able to run an exe program from it, so it would need to basicly be able to run windows, just without logging in, kinda like how you can with ubuntu on a usb with wine configured.
Yes, but BIOS needs to support this:
BIOS must be UEFI
BIOS boot manager should try to load from USB before HDD/SSD.
Such applications are called UEFI (shell) applications and can be created via EDK II.
These apllications run at ring 0 on Intel architecture.
