So about a year ago, my cousin and I started a world on Minecraft Xbox edition. This was quite a long time before Nether Fortresses were added. We still play on that world. Unfortunately, we can't complete the game legitimately. You might be asking, "Why not?" Well...... without Nether Fortresses Blazes cannot spawn unless you go into Creative Mode and spawn in Spawn eggs. And without blazes, you can't make Eyes of Ender which you need to find a stronghold PLUS you need 12 of them in order to activate the End portal once you find it. We also can't really make potions either. Does anyone know a way to find a Nether Fortress even though the chunk generation is relatively old?
You can reset your nether without disabling leaderboards and achievements (under "More Options" when you load your world). What this will do is give you the more modern nether for that same seed, which will contain a nether fortress. However, if you have built anything in the nether, you will lose those structures. There is no legitimate way to enter creative mode without disabling the leaderboards and achievements for that world.
From what I've seen on you Xbox profile, you're only missing the "When Pigs Fly" and "On A Rail" achievements. Considering that the latter takes a bit of work and resources, why not just build a long enough rail to get that achievement now, and then - if possible - the last achievement? And once you have those - or at least "On A Rail" - start a new world that will have an End Portal?

... or after getting the remaining achievements, go into creative mode and build an End Portal. Then, flip back into survival mode and when you activate the portal the End and Endragon will generate even in an older world. It's only construction of the Portal that requires creative mode, but once you get all the achievements, the only thing you miss out on is adding to your mining and farming tallies on the leaderboards for that world... which are notorious for resetting anyways. There is no achievement for slaying the Endragon and there is no mention of the Endragon or End on the leaderboards, so you won't be missing out on anything in that respect.
THEN, AFTER the world generation format changes and jungles are added in the next update, generate a new world. Many of us are anticipating that this will update MAY be the last one where we have to start a new world to incorporate new biomes, since no new biomes have been added to the PC game since jungles.
The solution involves backing up the savegame file to an external USB device, renaming the backup, then loading the renamed world in Creative Mode. Using this method you get an exact copy of your current world, not just the plain world as it was seeded, but including any changes you have made to that world since it was created. Before you begin, make sure you have a USB thumb drive or other USB storage device that is formatted for use with the XBox. If you don't already have one set up for the XBox, any data on the device you intend to use will be lost when formatted for use with the XBox.
Here's how it's done...
1. Exit out of the game first (don't forget to save) and return to your XBox main menu.
2. Go to Settings > System > Storage and select the device you saved your Survival Mode world to originally, most likely to your XBox's hard drive. Then go to Games and Apps > Minecraft and locate the savegame file for the Survival Mode world you want to clone, then select it (A), and Copy (A) it to the USB device.
3. Go back to playing Minecraft, and when it asks you which device to load your world from, choose the USB device instead of the hard drive. Load the game using Creative Mode rather than Survival Mode, and select the Host Options if you want them.
4. Once the world loads, save and exit back to the Minecraft menu. Go back to the load screen and rename the save file. I rename mine the same as my Survival Mode world, but with a (CM) at the end to denote Creative Mode. Renaming is vital if you intend to follow the next step, which is optional.
5. Exit out of the game and return to your XBox menu, and follow step 2 above again, but this time copy the savegame from your external USB device back to your XBox's hard drive. You should now have two exact copies of your world, one in Survival Mode and one in Creative Mode.
This procedure can be done over again whenever you have made major changes to your Survival Mode world, so that you can keep your Creative Mode copy in synch. I hope this proves useful to someone. I know I'll be doing this often.
This solution was for a different problem, but it would work well in the OP's case too. Make a copy of your world by using another storage device, rename it, copy it back to your main storage device. Then you have 2 copies of your world, one with full Survival status (where achievements and leaderboard positions can still be earned) and one which you can modify in creative mode.

The problem is that I only have 1 storage device and the built-in one has like 37MB of space left so it is probably too small to even be able to install MC and run the world.

Cobra's solution has a real risk attached to it anyway. After you rename the world on the hard drive and attempt to save the unrenamed one back from the USB, sometimes the game will indicate that you already have that world saved on your hard drive... and if you try to cancel out of the oversave, it can, on occasion, trigger the deletion of the world saved on the hard drive.
I didn't know the game had such an unforgivable bug in its I/O code. Loss or corruption of data should be fixed immediately upon discovery in any game. Good thing I keep 3 backups of my world files. I'm not sure if it makes any difference, but the method augurnz described calls for renaming the file on the backup device, after copying it there, then copying it back to the HDD (never renaming the file you save to constantly on the HDD). In my case, I have not had any problems so far.
Edit: OK, this is what I've decided to do to combat this shockingly bad issue. (I realize that others with a single storage device are SOL. I recommend having at least one backup memory stick. These things are fairly cheap.) I use my internal-memory device to store what I call the control version of my world backup. It always has the latest backup. Then I have backups from the 2 most recent dates on my other 2 backup devices--an old-style memory card, and a USB stick. The latest backup's thumbnail image will always match the thumbnail of what's stored on the internal memory. This way I know which backup is the most recent. It is necessary because the save files only show the creation date, not the modified date. With me so far?
So what I'll do is delete the renamed world from my main device--the HDD. I will only use the renamed file on the internal-memory storage device. That way, I'm risking only the control backup file, leaving the original (and newest save) and 2 other backups perfectly safe--hopefully. This bug doesn't search and destroy across storage devices, does it?

I agree. It's a really irritating circumstance and I can only guess that it's in there to try to prevent people from having two copies of the same world on the same hard drive... perhaps to try to prevent file sharing. I haven't deliberately tried to test it for quite awhile now... I'll have to make some worlds I can scrap and see. I use my USBs really just for emergency backups when something has gone wrong with the hard drive copy, so after this error happened to me a few times, I've gone to deleting the "botched" hard drive copy first and then copying the backup from the USB to the hard drive.
I'll try running some intentional tests today and let you know precisely when it happens and when it doesn't.
ETA: They must have fixed the issue since it is now working regardless of whether the rename is done on the hard drive copy or on the USB one. Once one is renamed, the file from the USB can be copied back onto the hard drive without any apparent conflict. YAY!
Hmm. Okay. Now I'm not sure about anything. I've read all sorts of things about this out there, and here. It was fixed; it wasn't fixed; it was supposedly fixed, but the fix didn't work . . . I guess I'll just assume you're right in you latest post, ignore your earlier post, and be very sure to keep multiple backups. Can never go wrong with backups.

I agree - I'm going to continue to keep multiple backups... cycling through multiple USBs... just in case. After you posted, I tested it both ways a few different times and with a few different files and never got the error message. The copies went smoothly every time where I used to get the error more often than not. I wonder if the error wasn't perhaps in the Live dashboard end of things?
Also, my cousin has been telling me all we have to do is walk a couple hundred blocks to a unloaded chunk which will then spawn in an End Portal
Your cousin is, quite frankly, out to lunch. Since you've probably already walked over your entire map, the terrain for the map has already been generated. If you do have completely unexplored areas in your map, then there is a slight (read SLIGHT) chance that the end portal might spawn in that area... but that depends on if that area happens to be where the end portal would spawn if a world was newly created today using the same seed string.
