Make sure your USB drive is plugged in and go into bios and then make sure your 1st boot is from USB drive and do a restart your laptop should than boot from USB drive.
I agree with vacuum-tube. You'd be even better off with using Puppy as a portable on a flash-drive, simply because it's smaller, takes up less room (you can stick 'er in your pocket, or even put it on your key chain).....and most important of all, because Puppy was designed, right from the word go, to run from a flash-drive.
Create a Puppy USB install on a stick, then do as vacuum-tube says; insert the USB before you power-on, then go into the BIOS straight away, and set boot priority for the USB drive first. Some machines recognise USB flash drives as 'USB-HDDO', for some reason.
Or, you could simply copy your existing install across to your flash drive.
1) Prepare the flash drive first. Make sure it's plugged in, and the icon is showing on the desktop.
2) Go to Menu>System>gParted. Select to show your flash drive from the list you'll get, and hit 'OK'.
3) Right-click on any partitions showing, and then 'Delete'. Now click on the big check-mark in the Menu bar, marked 'Apply'. You'll be asked to confirm that you wish to do this, then it'll give a final warning about loss of data. 'OK' all this.
4) Wait until gParted has finished that, then right-click > 'New Partition'.
5) Select ext3 as the file system type. Everybody says ext2 is better for flash drives, as it cuts down on read/write operations, but it corrupts rather easily. Ext3 will allow you to recover from mistakes!
5a) Right-click again on the partition you've just created, and choose 'Manage flags'. A small window will appear, and you want to tick the check-box for 'boot'.
6) Give it a 'Label' if you want, then exit gParted.
7) Back at the desktop, click on the drive icon for your flash drive. This will open a blank Rox-filer window, containing one item; 'lost + found'. That's your recovery directory.
8) Now, click on the drive icon that contains your Tahrpup install; it should come up as '/mnt/home'.
9) Highlight everything in this partition (except 'lost + found', if you already have one). If not, highlight the lot.
10) Click (and hold) on any item in /mnt/home, and drag it across to the window for your flash drive. Release the mouse button; a small window appears, with four options. 'Copy', 'Move', 'Link(relative)', 'Link(absolute)'. Choose 'Copy'.
11) Rox will now copy the entire contents of your partition across to your flash drive, including your save-folder, which contains all your settings, and configuration). If you're using a sub-directory, rather than a partition, the process works just the same.
12) When this is done, you now need to make the flash drive bootable. Menu>System>Grub4DOS bootloader configuration.
13) Let it probe your drives. A window will appear, listing your drives. Highlight the option for your flash drive, and tick the checkbox on the right for 'Search within this device only'. Hit 'OK'.
14) The next window should list your Tahrpup install. At this point you can edit and re-name if you wish. You'll see an entry for Windows; don't worry about this, it's standard across all Puppies. All you need to know is that Puppy's version of Grub4DOS has been specifically tweaked to work with Puppy's admittedly unusual way of doing things! Again, hit 'OK'.
15) The next window asks if you wish to install Grub4DOS to this partition. Click 'OK' or 'Yes'.
16) The final window will tell you if it's been successful. It should have been, and you can now exit the program.
You've now copied your existing Tahrpup install across to your flash drive, and made it bootable..! Now, simply follow vacuum-tube's instructions, and mine, as above.
It should work nicely. Let us know how you get on, please; if you get stuck, post back again, and we'll try and sort things out.....it's a relatively simple process, TBH.
(Says the 'expert'..! )
Edit:- At a guess, it sounds like your laptop boot problem is more of a UEFI boot issue, especially if you're running Windows 8.1... I believe you need to disable not only 'Fast Boot', but 'Secure Boot', too; and that, I'm afraid, we can't help with, without knowing the make, model, and specs of your machine. If you can provide that, we can quite possibly tailor our advice a wee bit more accurately.
